Hi all,
I have an image(gray scale) whose pixel intensity values ranges from -0.5373 to 0.4744. I would like to change the intensity value which is lesser than 0 to 0. Can any one help me to solve this.
Thanks.

Say your image is x,
x(x<0) = 0;

No, you don't need all that reshaping stuff. "x(x<0)=0" is sufficient to work on the whole 3D matrix (e.g., a color image) - no reshaping is needed.

use a suitable transformation to change the intensities from ( 0,255) to (65,180).

Are you sure you posted to the correct six year old question? Not sure what your answer has to do with the original question about clamping the signal to zero.
