i using asp.net 4.0 , mvc 2.0 web application. project requiremrnt have use server side control in application not possibl in noraml case. ideally want use adrotator control , datalist control. i saw few samples , references in codepleax mvc controllib howwver found less useful. can tell how utilize theese controls in asp.net application along mvc. note: please provide functionalities related adrotator , datalist controls not equivalent functionalities thanks in advace. mvc pages not use normal .net solution makes use of normal .net components impossible. a normal .net page use event driven solution call different methods service side mvc use actions , view completly different way handle things. also, mvc not use viewstate normal .net controlls require. found article discussing mixing of normal .net , mvc.

Computer Vision: Detecting Parabolas using the Hough Transform -

-

papers have been written describing how hough transform can generalised detect shapes circles , parabolas. i'm new computer vision though , find these papers pretty tough going. there code out there detection more want. wondering if briefly describe in bullet points or pseudo-code how hough transforms used detect parabolas in images. amazing. or if knows basic explanations online haven't come across enough :).

thanks :).

interesting question. looks great resource. included summary (loosely quoted). see source mathworks @ bottom of answer - matlab has houghlines , houghpeaks functions useful you. hope helps.

  • run edge detection algorithm, such canny edge detector, on subject image
  • input edge/boundary points hough transform (line detecting)
    • generate curve in polar space (radius, angle) each point in cartesian space (also called accumulator array)
    • extract local maxima accumulator array, example using relative threshold
    • in other words, take local maxima in accumulator array values equal or greater fixed percentage of global maximum value.
  • de-houghing cartesian space yields set of line descriptions of image subject
