   Hough Transfromation , Question.
  Hello good people..Currently i am working on hough transform for line detection. I could do the hough transform correctly. But now correctly finding the lines from hough space is problem. Anybody knows any method other than thresholding the hough space ?thanks ,KDworld   
  finally i made some method for my application specific purpose.. i picked a value from hough space only if the surrounding pixels value is less than the current pixel. After that i sort the hough space based on the highest peak. ;Quote:Original post by kdworldi picked a value from hough space only if the surrounding pixels value is less than the current pixel. After that i sort the hough space based on the highest peak.If by "peak" you mean one of the local maxima you select in the firt pass, by processing only strict local maxima of the histogram you perform useless work to find them (the discarded pixels would have been discarded when finding the maximum of all bins, with less comparisons) and you can suppress results when adjacent bins happen to have the same value. For example, with a 1D histogram like 2-2-2-3-3-2-0-1 you would select the rightmost bin, almost the worst one, rather than either of the middle ones.Moreover, you don't need a full sorting to find the maximum value in the array and all its locations.Correct processing of Hough transforms is better performed by detecting ambiguous solutions and/or by not using unreasonably small bins that are subject to noise.
