If the input is the name of a color, a search is done to find a matching name, and the corresponding RGB triple is returned. Ensure the custom projectAndReshapeLayer is configured for your encoder latent size - in the example the projectionSize is 7,7,64 but for the same network on 200x200 images I would expect this needs to be 50,50,64. If the input is a color index (1-21), it is converted to an RGB triple If the input is an RGB triple with elements in, it is scaled by The calling program without modification. If the input is an RGB triple with elements in, it is returned to RGB is a length-3 vector of RGB components that can be used as a color specifier with any of the Matlab graphics functions. See the code for the list of color names. Note that some colors have more than one name, in which case any of these may be used. index_or_name can be a color index (whole number from 1-21), a string containing the name of a color in lower case, an RGB triple with elements in, or an RGB triple with elements in. For eight of these colors that have more than one common name, the program accepts alternative names, reducing the memory burden on the user. RGB() allows the user to access a set of 21 colors via their common English names. Note that MATLAB assumes that for uint8 images the values are between 0 and 255, while for double images, the values are between 0 and 1, so they would need to be scaled.The Matlab function RGB() converts a color index (whole number from 1-21), English name of a color (string), or RGB triple with whole number components in into an RGB triple with real-valued components in. I just want to get the RGB value for all the 10 values. To have a lossless conversion, you should use the double datatype. So I have a random data with 10 different values, each values may be represented by 3 values (R,G,B). For a testimage of mine, the maximum difference between RGB and RGB1 was max(abs(RGB(:)-RGB1(:))) Note that if you are using uint8 as type for RGB, then YCBCR and YUV will be uint8 too and the conversion will be lossy. YCBCR1(:,:,2) = YUV(:,:,2) / 0.872021 % U -> Cb What I have done thus far to create RGB images is to just load a white image and seperate the red green and blue components from this image and combine them. The example displays each color channel as a grayscale intensity image and as a color image. YUV(:,:,3) = 1.229951 * YCBCR(:,:,3) % Cr -> VĪnd to convert it back, use YCBCR1(:,:,1) = YUV(:,:,1) % Y -> Y This example creates a simple RGB image and then separates the color channels. Default color, specified as an RGB triplet. YUV(:,:,2) = 0.872021 * YCBCR(:,:,2) % Cb -> U RGB Default color1 1 1 (default) RGB triplet. Answers (1) Atsushi Ueno on at 13:45 Ran in: Theme I imread ('peppers. The rgb2gray function converts RGB images to grayscale by eliminating the hue and saturation information while retaining the luminance. I want to perform the ANOVA-n with outcome (y) as PHSGrades, which are letter categorical currently, based on multiple factors, such as MATGrade (also letter categorical), SEX, ETHNICITY, and AGE (which falls into one of 5 ranges: 0-17 18-21 22-25 etc.). To convert an RGB image to YUV, you can thus use RGB = imread('11111.bmp') I need some help formatting a table (attached) of student grades for an ANOVA-n analysis. To convert between RGB and YCbCr, MATLAB offers the functions rgb2ycbcr and ycbcr2rgb.
