Today, was not good for me. Whole day I was trying to do further image processing in octave, But do nothing. There were many functions But none function gave exact result. But some functions of image processing that I done earlier are possible in Octave, such as loading and displaying the image, Converting the RGB image to Gray scale image, plotting on the image by intensity, Finding the frequency of image , finding size of RGB image and displaying image only in one color by clearing two matrics of RGB image.
But I will try further operations in image processing.
