hi
actualu i have to convolv the same image with gaussian kernal with 3 different values of sigma. i have done this work. the next is that take difference of (log of originol image)-(log of convolved image) this operation is performed on all the three values separatly i have done this too. after this i have to divid all the three image swith 3 and then add them it gives me an enhanced luminance image in matlab and nearly similer results in L.V. but after that i have to done contrast stretching by applying the equation:
image pixel-min value of pixel/(max-min). and after that i took the ratio of this result to the original image. but before this i have to use if statement that if (pixel of resultant image<pixel of originol) then result pixel=original.
here comes a problem... in mat lab i have got some values of originol and some of resultant image but here in l.V i got all the values of originol because originol image has values from 0 to 255 but the resultant image has values in points that gives me ratio of both in the form of all ones and i can not get my result.
if i do not do contrast stretching and only take the ratio and multiply ratio with rgb image of the luminance image i got an image with abrupt spreading of colours that makes no sens.
it is my last step to multiply the ratio with rgb image to get enhanced image. i have done same work in matlab but it is not being possible for me in L.V.
kindly tell me a solution. i am not attaching VI because its too large and i think it is so time consuming to understand it,
if some body can help me then tell me specially... Klemen! kindly tell me some solution.
THnx
