IMSH - Image Processing learning shell

I have been started new public open source project: IMSH for studying image processing. This is the SIOD Scheme based shell with several test purpose scripts. All algorithms are C coded and Scheme scripts are used to drive and test C algorithms which now are:

• Black and White
• Greyscale
• Negative
• Convolution Matrix
• Channel Mask
• Greyscale Approximation
• Pixalization
• Median filter
