Hello ! i have to apply morphoogical operation on the biomedical image...when i apply Laplcain of gaussian before the morphological operation then result is just a black image......what is the problem in this code.
img_BlueRation=imread('imgage');% img_BlueRation is the input image
Gauss_filter = fspecial('gaussian',[13,13],4.0);
img_Gauss = imfilter(img_BlueRation,Gauss_filter,'symmetric', 'conv');
Laplac_filter = fspecial('laplacian');
img_LOG = imfilter(img_Gauss,Laplac_filter,'symmetric', 'conv');

It worked for me when I used cameraman.tif. Try casting to double right after you read it in:
img_BlueRation = double(img_BlueRation);

Maybe everything got filtered away. Post your image if you want me to try it.
