Difference between the intensity and the gray scale value

Hi I am a new learner of vision of NOR, please bare with me.

1. I'm quite confused by the terms of light intensity and pixel gray scale value. Can someone explain the difference to me? Or are they the same thing?

2. I'm currently treat an image in grayscale (I16) file. The number of bits of the image is 12 Bits. But I saw that someone used IMAQ polygon with the number of Classes as 8192 (13 Bit), don't know why.

Thank you, Jane

Hello Jane,.

1 OK, grey scale and intensity are the same thing.

2. the number of class you choose is an appeal from the judgment.  By increasing or decreasing the number of more or less granular classes, the histogram becomes.  Without a context, I can't speculate on why someone use 8192 classes.

    The media have a meaning that helps you tell the difference between and [parent].
    <>means that the value is bound to the entity, the data are shared by all parents of this entity.
    [] means that the value is specific to this parent/child 'node' and it is not shared by the other parents during consolidation.
    Keep this in mind when you choose to make a newspaper on or [parent adjs].

  • The difference between the strength of the signal and quality?

    Hi all

    According to the Cisco documentation

    Low RF signal strength does not mean the lack of communication.

    The quality of the signal is low means poor communications.

    If someone can explain to me the difference between the power of the signal and the quality of the signal?

    In accordance with my AP home I see that this signal strength is measured in numbers like 50% or 100%.

    But what is the quality of the signal and how to measure me?

    Thank you

    Mahesh

    Big question...

    First, let's look at the notion of signal quality and strength... Suppose for a minute you're front row at a rock concert right next to the speakers. Sound is loud, you can't hear anything else that scream. It is an example of a strong signal but poor quality.

    As for the signal and the noise of measurement or should we say quality of signal. Providers sometimes give you a % or dB scale when ranking signal. You can't really do headers or tails of the % scale because each vendor has % different measures. But check your access point, because you will be able to change in dB.

    Look at dBm. At the moment my client shows:

    Signal - 59 dBm

    Noise - 98 dBm

    The dB scale is simple. More PB the STRONGEST signal. You'll see - 59 of the signal is good, in fact, I'm about 50 feet from the AP. If you are under the ap you will get as a - 30ish. Noise, we do not want to be noisy, if we want to see the noise to-100. More low is the dB of noise as loud noise.

    So we're back out the example above. Next to the speaker, you're showing tell - 30dBm, but your noise can be as - 70dBm...

    Does make sense?

    Normally, you want to see your signal not exceeding 67 - not for voice or - 76 for the data. And your noise should be greater than-90.

  • Y at - there a big difference between the base of the m3 and m5 models?

    I had my m3 2016 Macbook for a week so just thought I would ask so that I have time to exchange it if need be. I wondered outside storage space, y at - it a big difference in processors Core of m3 and m5? Apple uses a "customized" version of the processors? I ask because Apple lists the m3 1.1 Ghz but not apple models are call at 900 mhz.

    The processor is clocked at 1.1 Ghz. There are different models made by Intel, including that which is supposed to be clocked at 900 Mhz. Apple does not use a customized version of the CPU. The differences between the M3 and M5 model is displayed on the Intel Web site. Among the differences are the M5 is clocked at a higher speed and the M5 is generally about 15-20% faster than the M3 at the same clock speed.

  • What is the difference between the export photos and pictures of unmodified export

    I'm trying to export my library of photos of 30 GB on a hard drive. When you choose file > export gives two options: export the Photos... and export Unmodified Original...

    Is there a difference between the two options?

    When I export the location data is backed up?

    The original unmodified are image files full-size that have been imported into the library at the start.

    Export Photos will give you the edited version (if it is edited).  Also, you will have a chance to change the size of the file (Mbs) and/or the image (pixels) size when exporting and to change the JPEG, tiff or png.

  • Difference between the Tecra A, M and S series

    Hello
    What really is the difference between a, M and S Tecra series? Which should I choose?
    It is obvious that the Tecra is supposed to be a high-end standard in the range of the portable Toshiba, but why they do different Tecra series?

    I'm sorry if this has never asked, but can't find the answer.
    And thanks to all who responded.

    Regars,
    -nov

    Hello

    I am user Tecra M and each series has my own opinion design and hardware configuration. The availability of different series can be nice for potential buyers and costumers let them choose the preferred product.

    If you need Tecra for business, I can really recommend laptop Tecra. I use it more than two years and it works like the first day. It is very important that you know exactly what you want to do exactly, and you can choose your favorite.

    If you want to write what you expect from a laptop. It will be perhaps easier to give you a specific recommendation.

  • Difference between the G20 and G25 models

    Hi people!

    I searched your laptop and I was amazed by the Qosmio.
    When I was going to order it, I noticed that there are many models of the G20 with different specifications. Also, I found G25 on internet research and found no difference between the G25 and G20 except receiver TV G25 is NTSC and G20 was released on March and G25 was in June. Instead, they have the same specifications for the hard drive.

    I live in the Portugal and the model Qosmio I can find that this is the G20-118. I was looking for the model that has 2 x 100 GB SATA HD, but cannot not thought about it.

    Internet research I found Qosmio G20-111 which has 2 x 100 GB SATA HD, but on the web page mentioned that it was a Pentium III processor (ridiculous, isn't?). I was looking for more reliable information.

    Already searched for toshiba pages and found no specifications for all models I found 490LS on the research on the web as the G20 - 102, 105, 106, 108, 109, 111, 118, 123,...

    Can someone help me with this? Are there any reliable web page where I can see the differences between the models? is there a .pdf or anyone who can please give me some advice?

    Money is not a problem at this time to acquire the laptop, I'm looking for only the laptop performance more!

    Best regards

  • What is the difference between the HX - 90v and HX - 80 coming cameras?

    What is the difference between the HX - 90v and HX - 80 coming cameras?

    Thank you!

    I'd say it's supposed to be a fill, a little brother to the HX90v

    It removes the control ring and the GPS, and I think the rest is the same.

    It is for those who want the HX90v but the price is a bit steep for the compact range, and they need not necessarily GPS or the ring of command, just a camera that works.
    This kind of thing, at least to my knowledge.
