I am attaching a figure which shows the histogram of an intensity image(0-1)scale. Can somebody interpret the graph so that i can understand it in a better way. Thankyou. Nithya merin

Your image values range from 0 to 1. Perhaps you used im2double to scale a floating point image to the range that most MATLAB functions that operate on floating point images like. The bar chart represents the frequency of occurrence of that intensity value. So you have a lot of dark pixels and not as many bright ones.

No. Why should it. As long as you know that it's an image in the range 0-1 and do your operations with that in mind, it should be fine.
