Re: Is it possible to crop two rectangles out of standard shapes

Thank you Snigbo, I appreciate your suggestions! I include the following four images on a dark background, the variables (as I hope are clear to see) are [1] different lighting (flash and no flash in this example) and [2] whether the cartridges are touching or there is a gap between them: https://ww...

Re: Perform histogram analysis on certain image area only

Thank Fred. It does not give me the colors in those formats with either of this options. For the practical application at hand this is not a problem, as I will know what is a stripe and what is a background. And actually it is an advantage to have both the types of segments for analysis. In fact I w...

Re: Perform histogram analysis on certain image area only

Dear Fred Pure magick! And just what I ordered. FWIW, on my platform this statement was never true: `if [ "$color" = "gray(255)" ]; then' because for example: ${arr[0]} = 0: 123x88+0+0 +61.0,+43.5 10824 But no matter, I removed it because I want to generate images of the different pieces. Thank you ...

Perform histogram analysis on certain image area only

Hi, I have images with certain lines or bands on a ~white background. First I want to analyse the image to define the area of these lines or bands and then I would like to perform an analysis of a certain color range on that defined area only or those defined areas only. What might be a good strateg...
