Colourspace Histograms

Colourspace Histogram's: I have managed to create a solution for appending images in open CV that lets me now display the histograms for different colour planes on one image. The results are shown below:



HSI



LAB



RGB






HSI



LAB




RGB








HSI



LAB



RGB












Idea's for Future: Do the same comparisons for hsi and lab with the training set and see if they have any useful comparisions with the chi squared results or if they ahve any cleaner results that may be used. I.e replicate rgb functionality in hsi and lab and compare classification results.


Problems Ran into this Week: so far i've not been able to figure out a way of only creating histograms on a portion of an image, using the set window size. However i think today i may have stumbled upon something called setImageROI which operates only on a selected region of an image, however to do this over an image in the same way as a convolution would be very computational expensive and this first stage is supposed to be a quick check of a present target or not...and even before this inclusion it is already quite slow with the multiple operations being computed.
