WebThe RGB color space represents images as an m -by- n -by-3 numeric array whose elements specify the intensity values of the red, green, and blue color channels. The range of numeric values depends on the data type of the image. For single or double arrays, RGB values range from [0, 1]. For uint8 arrays, RGB values range from [0, 255]. WebTo actually use the adapt_rgb decorator, you have to decide how you want to adapt the RGB image for use with the gray-scale filter. There are two pre-defined handlers: Pass each of the RGB channels to the filter one-by-one, and stitch the results back into an RGB image. Convert the RGB image to HSV and pass the value channel to the filter.
