20150908 05:09:11 0600  asked a question  Pixel intencity difference in opencv and Matlab I am trying to implement various Matlab functions rgb2lab in opencv. I got output images(in opencv) similar to Matlab. But their pixel values are different. For example output pixels values of 2x2 pixel image:

20150907 05:20:35 0600  commented question  Implementation of various matlab functions in opencv @LBerger: Sorry, I said I can save the image using ' imwrite' function. But I cannot show my output image using 'imshow' function(This is my problem). 
20150906 22:35:16 0600  asked a question  Implementation of various matlab functions in opencv I am trying to implement various Matlab functions in opencv using c++. These are the functions lab2uint8 , lab2uint16 , lab2double , xyz2double , xyz2uint16. These conversions I did by 'convertTo' function. For example: lab2uint8 conversion ' lab.convertTo(Result,CV_8U)' . Then I can't show my Result image by imshow function. But I can save the Result image by imwrite function. I know I am troubling you by repeatedly asking similar type of questions, sorry for that.

20150905 12:23:24 0600  asked a question  How to find the color space of an image I am trying to do diffrent colorspace conversion on images (rgb2lab,rgb2ntsc..etc) in opencv using c++. After the conversion I just compare my output image with Matlab output image. Comparison is just done by normal vision. but I know that in the case of images normal vision comparison is not accurate. How can I find which colorspace(rgb,ntsc,lab,xyz) my image belong to?. Any standard method or technique for finding the colorspace of a image? I am totally new in image processing domain.So please give proper guidance in image processing using openCV...

20150905 00:12:27 0600  asked a question  Implementation of rgb2lab in opencv using c++. implementation. Then I did another implementation.Here is my code: Both implementation results are not similar to Matlab output image. Please find the 3 image files : 1)my first output image(using cvtcolor),2) second output image(using above code) and 3) third matlab ouput image. Please anyone help me to find the correct way for implementation.

20150904 14:10:19 0600  asked a question  Implementation of rgb2xyz in opencv using c++ I am trying to implement matlab rgb2xyz function in opencv using c++. I used cvtColor function for implementation. But my output image is not similar to Matlab output image.Should I use any other function or operations on image ?Here is my input image ,matlab output image and my output image. Hai... I got 1 more code for the implementation of rgb2xyz.But it gave me black output image. Here is the code.

20150904 05:00:29 0600  asked a question  Implementation of Matlab function rgb2ntsc in opencv using c++ I am trying to implement rgb2ntsc colorspace conversion in OpenCV using C++. I have done this for the implementation of rgb2ntsc. But my output image is not similar to the output of Matlab's rgb2ntsc function. Here are my input image, output image and matlab output image. Can I do any additional operation?
