I'm doing my project in image processing domain. The title is efficient color quantization based on generic roughness measure. and I have completed the first existing approach present in my base paper that is histogram thresholding based quantization....
steps,
1.read the image
2.convert rgb to gray
3.split image into 2 equal size
4.plot histogram of 2 images
5.find difference btwn images
6.find best threshold level
7.if diff>threshod=255 else diff<threshold=0
8.plot the thrshold image
9.do quantization of threshold image
10.compare original and quantized image
11.calculate mse and psnr
