Still I was trying to solve my problem. Actually i wanted to install new version of octave-4.0.0 and i download it from its official site. After downloading , I untar the tar file and configure it. But ./configure command gives error at the end. My friend ask me installing g++. But it did not work.
In the mean time, I search another functions of image processing which were given in the list. I found many functions which are possible without Octave-Forge package such as imdilate, imerode, imdouble(type conversion of image), ploting on image, imopen(morphology), imfilter, and tried to use them. But detail study of these function is pending. Still I am working on it.
