Hi. May I ask, how to define the mean value and std value for each image channel? My dataset consists of the natural staellite images, just use 0.5? Or compute the mean and std value for each channel of each image?
Moreover, can we set a parameter to make the CNN find the optimal parameter (mean value, std value or other weights/biases used in each channel) for the image processing? If so, can you tell me how to set the parameter?
