  • For example, if idx is 3, imread reads the third image in the file. If you omit this argument, imread reads the first image in the file. [A,map,alpha] = imread(...) returns the AND mask for the resource, which can be used to determine the transparency information. For cursor files, this mask may contain the only useful data.
  • Sep 05, 2019 · That is, the 5 unique values are 51, 102, 154, 204, and 255. A LUT with these 5 values is applied to the 3 channels (red, green, and blue). As such, each of the 3 channels will have 5 unique gray levels. If each channel has 5 gray levels, then the total number of colors produced by such levels is 5x5x5=125.
  • Dec 30, 2017 · It's actually only a single line of code, but there are some things you need to be aware of... like the fact that OpenCV will import all images (grayscale or color) as having 3 channels, so in order to read a grayscale image as only having a single channel you need to pass the arg 0 after the image location.
