The results of Match lost color

I use the node color model match looking for a model from a webcam. But the node may return one or two good results among ten times to win. For the other nine times, the node cannot yet to find the target. I tried to change a clearer webcam and adjust color weight, Mode Match Score, search strategy, color sensitivity, etc., for several times. But the problem persists, and the improvements are not significant (almost no improvement). Now, I want to improve the success rate in the match. What should I do? Thank you!

Try to extract the luminance plane and experiment with the algorithms of pattern matching in grayscale.

  • The results of contourc in MathScript does not match

    I have a simple ".m" file which I'm trying to convert labview code by using the Mathscript node.

    The matlab code is simple as follows

    % Read image

    IM = double (imread (image_path));

    C = contourc (im, [0.8 0.8]);

    I checked the latest Mathscript node. The 'imread' and 'contourc' are built-in functions supported. So far so good. So I put the code in the node (for contours in MathScript functions, I had three options: outline, outlines, contouris.) One contour is supported by the runtime, so I chose "contour").

    BUT the result of Mathscript is inconsistent from Matlab. From Matlab, it is a matrix 2 X 126, while since Mathscript, it is a 2 X 200 matrix. I tried others two strokes and contouris as well, same result.

    SO what is happening here. How should match the original matlab code with a function "contourc" in there? Thank you.

  • Use two temporary tables to assign 'color' to the results of the data

    Hello world... Here's what I'm trying to do, any help is appreciated of course...

    Data and Tables in the example:

    I have 5 dishes, each course has 2 assignments.
    with Courses as (
     select 100 courseID from dual union all
     select 200 from dual union all
     select 300 from dual union all
     select 400 from dual union all
     select 500 from dual
    ), Assigns as (
     select 'test100' name, 100 courseID from dual union all
     select 'test100', 100 from dual union all
     select 'test200', 200 from dual union all
     select 'test200', 200 from dual union all
     select 'test300', 300 from dual union all
     select 'test300', 300 from dual union all

    I need each assignment to get a color assigned to it according to its courseID. So my theory is that I have a temporary table with a list of colors; each courseID would be are they assigned a color, but my question is how can I assign each courseID a color without anything to join the temporary table? Once that each courseID has a color, I would join rights holders so that each assignment has a color associated with it according to its courseID.

    Can get it, or ask someone with the makeup of capacity change for you.

    Is the problem that you have more than 6 courses but you want to add color to them with only 6 colors, and it is unclear what courses can be included in the results of a given query?
    If so, you can do somehting like this:

    WITH     colors     AS
    (
         SELECT  'red' AS color_name     FROM dual UNION ALL
         SELECT  'blue'                FROM dual UNION ALL
         SELECT      'yellow'          FROM dual UNION ALL
         SELECT     'green'               FROM dual UNION ALL
         SELECT  'purple'          FROM dual UNION ALL
         SELECT     'teal'                FROM dual
    )
    ,     colors_plus     AS
    (
         SELECT     color_name
         ,     ROW_NUMBER () OVER (ORDER BY NULL) - 1     AS color_id
         ,     COUNT (*)     OVER ()                    AS color_cnt
         FROM     colors
    )
    ,     course_assigns     AS
    (
         SELECT  a.name
         ,     a.courseid
         ,     DENSE_RANK () OVER (ORDER BY  a.courseid)     AS course_num
         FROM          assigns          a
         INNER JOIN      courses      c     ON   a.courseid   = c.courseid     -- If needed
    )
    SELECT     ca.name
    ,     ca.courseid
    ,     cp.color_name
    FROM     course_assigns  ca
    JOIN     colors_plus       cp  ON   cp.color_id  = MOD ( ca.course_num
                                                 , cp.color_cnt
                                      )
    ;
    

    Typical power:

    AME      COURSEID COLOR_
    ------- ---------- ------
    test100        100 blue
    test100        100 blue
    test200        200 yellow
    test200        200 yellow
    test300        300 green
    test300        300 green
    test400        400 purple
    test400        400 purple
    test500        500 teal
    test500        500 teal
    

    It would be better if you could create a real table as colors_plus.

    If there are more than 6 separate courses in the output, then 2 or more courses can be coded in the same color, but no color will be used N times (N > 1) until all the colors have been used N-1 times.
    The assignment of courses coolors is arbitrary. Depending on how fancy you want to do this, you might want to do something more complicated. For example, you have 2 course with 10 lines of each and 5-course dinner with 1 row of each. The query above will have to assign the same color to 2 courses of differenct, and it can assign the color "blue" for 2 courses with 10 rows of each. The query above can be modified, if necessary, assign the colors in order of frequency, in order to ensure that two 10-line courses get different colors, and that the colors tend to be more evenly distributed. I'll leave that as an exercise. (Tip: use the frequency in the clause ORDER BY of DENSE_RANK.) To obtain the frequency, use the COUNT function analytical in a subquery. Why do you need a subquery? Discuss among you).

  • What is the disadvantage of savings WITHOUT color profile for the web?

    I have discussed this issue in another thread and a clear argument against saving jpg files * without * a color profile must be performed.

    I'm very annoyed with how much more red and saturated, all my jpg files appear in IE (which does not read the sRGB embedded profile) compared to FF (which is the case).

    I tried to save the image even with the inclusion of unchecked color profile, and of course, IE and FF are showing the same image.

    It seems to me that including color profiles with jpg are just an invitation for different browsers interpret the image differently.

    Why not just save them all, WITHOUT color profiles?

    The downside to this, what exactly?

    mjyeager wrote:

    ... IE does not read color profiles. The fact of FF. ERGO, in situations where a color profile is involved, the JPG will be different in each browser.

    True, without color managed programs and management the colors may not display an image in the same way. Except in the situation where the color profile describing the color of the image or the color values of an image without a color profile, by an extraordinary chance match the display capabilities of color of the device used by the program managed without colors.

    One of the problems that the addresses of color management is that all monitors will display the same color differently. Color management will make colors appear the same or as close as possible.

    A color managed program will send the RGB values of the color of the video card corrected to compensate for the differences between how your monitor displays color values and how they are perceived.

    For example, to help my Monitor wide gamut, when I create an image in Photoshop, with a red color pure R = 255, G = 0 and B = 0 and then do a screen capture, I can check how Photoshop sends these values to the video card. The result is R = 222, G = 65, B = 0 when I'm simulating an ideal sRGB display. So I can see how my colors appear on the screens of ideal sRGB. However, in reality, it is very likely to have a monitor displaying space sRGB color ideal without a color management, so to complete the color management chain, the other monitors that display my image must also have the appropriate color management to compensate for the differences in screen and display correctly RGB numbers representing the color that I see on my screen.

    mjyeager wrote:

    ... However, if the JPG has no color profile, image shows exactly the same way in both browsers...

    Who will most likely be a bad smell, which means not repoducing the expected color which is always the case with the browsers managed without colors.

    ... Now, let's say this image - which looks the same in both browsers - is too hot. I can load it in Photoshop, change its hue and re-save is more what I'm looking for. The resulting image will then out - in the two browsers identically - the way I want to...

    Yes, the image will be the same in both browsers on your and any other monitor but the colors that you create (edit) will examine the way which only see you them on your monitor.

    mjyeager wrote:

    ... Now, what I think you are trying to do, is that I have no control on what are the conditions of viewing on the OTHER end (i.e., visitors to the site). They could range wide monitors, cheaper monitors, running MAC or PC, etc...

    I don't remember talking about this earlier, but yes, it's true.

    mjyeager wrote:

    ... It's true. I have no control over that. However, how including the color profile sRGB with the JPG would give me more control over these things I would not include? Unless you had to tell me that browsers arbitrarily apply a random color profile when in the absence of one, I am simply not understand how including the color with the JPG profile performs one another act that ensure that the picture is completely different in FF it does in Internet Explorer.

    You who are absolutely wrong. Color management is not to have any control over how other devices are setup, calibrated, etc.. As I said earlier make sure you communicate the colors scheduled correctly or as close as possible, as long as you and the destination use the proper color management. This means that the embedded profile FF will display correctly the planned colors while IE will not. If you do not include a color profile with your image both FF and IE will not display correctly the planned colors but they will be equal in that.

    mjyeager wrote:

    ... I understand the need for color profiles to print. In fact, my printer insists on the details when it comes to color profiles.

    But for the web? I'm still not understand where the downside is to omit the color profile. It's not like the browsers get CONFUSED when it is not included. Or that the colors will start randomly from refreshing one page to another.

    I am really trying to understand what you are saying here, but still haven't.

    In addition to what Marian said:

    If you create the colors using an sRGB display ideal (given the color management on your system works properly, it can be simulated by color of Photoshop on your range management widescreen when you assign the profile sRGB color to the image) and then on any ideal sRGB display, it will look the same you see on your screen regardless if it's with or without embedded sRGB color profile. However, in reality, it is unlikely to have a monitor, sRGB, display of the ideal space of sRGB color without color management. Now what does this mean in practice? Assume that users interested in, using the IE managed without colors on a PC with the Windows default color management. In other words, color management programs are told by the system monitor displays the ideal sRGB space, which is very likely to be the truth. Then users with this configuration with sRGB monitors will not see a difference between IE and FF when viewing your image with or without sRGB profile, the colors are not very likely to be the same that you see on the screen, but with the difference that is more likely to be accepted depending on how close to the ideal color space sRGB these monitors are. If some of these users with this configuration have wide range monitors, then the image will always be the same with or without sRGB profile, but with a very unacceptable difference of how you see it on your space to sRGB sumulated - strongly supersaturated.

    For users that have the color correctly managed systems, when the image is saved with a sRGB profile, it appears color managed programs such as FF the same or as close as possible to the way in which you can see on your monitor. Programs run without colors the case remains the same as that described above.

    A little history on how standard sRGB was created. It is a standard, including more things, but above all defining an abstract color space. It was created sometime after that the market was already flooded with computer monitors, and the creation of ideal sRGB color space was based on an average PC monitor display capabilities over time. After that the manufacturers used this standard sRGB as a target to create monitors.

    UN-color of programs run on PC have been created and tested using sRGB monitors so that they can't be considered reliable for showing intended to display colors if the images they use have been created using an sRGB they will be in the stadium of this range of sRGB.
