2015-11-06 04:00:28 -0600 | commented question | coversion of image from uchar to float Sorry guys, Actually i was not getting proper output so i was doubting my image conversion from uchar to float, the logic for conversion which i arrived after a pretty long discussion with @berak is right. the problem which i rectified is with the Logic i applied for image processing @boaz001 Image processing i m doing on image is to findout minumum of RGB in an image and make it a single channel image, after this Add a patch to image with patch size of 15x15, and find minimum value of current pixcel in that patch, then move the patch further. This is the image processing Stuff i m doing. Error which I encountered during image processing is, the output should be a Dark Gray Scale image, but what I was getting is a Full Blank image as that of Blank Computer monitor after shut down |
2015-11-05 01:14:39 -0600 | commented question | coversion of image from uchar to float @berak, the reason i want to convert image into float is coz the processing of image will be more precise. After that previous disscusion we had on the same topic, i use the logic for conversion what we discussed then, but i t seems to be failed at the time of image processing |

2015-10-28 02:28:38 -0600 | commented question | Problem in conversion from float* to cv::mat That's great..!! Its working.. But how do i convert back to cv::mat(string), such that i can print an image using imwrite my plan was to convert an image from cv::mat to float*, do some image processing, again convert back to cv::mat and print it for converting it to cv:mat i m using this is this fine?? i mean, am i heading in correct direction?? |
