 Why does one use MSE as a measure of quality. What is the scientific/mathematical reason for the same?2 AnswersMean-Square error is an error metric for measuring image or video quality it is popular video and image quality metric because the analysis and mathematics is easier with this L2-Norm metric. Most video and image quality experts will agree that MSE is not a very good measure of perceptual video and image quality.The mathematical reasoning behind the MSE is as follows: For any real applications, noise in the readings or the labels is inevitable. We generally assume this noise follows Gaussian distribution and this holds perfectly well for most of the real applications. Considering 'e' follows gaussian distribution in y=f(x) + e and calculating the MLE, we get MSE which is also L2 distance. Note: Assuming some other noise distribution may lead to other MLE estimate which will not be MSE.

 How would you code up a custom rectangle detector?4 AnswersI suggested something about matching intersecting hough lines.Hi... Could you plz explain what is a custom rectangle detector...I hav my interview with Amazon on monday ... plz helpBy a custom rectangle detector I mean how would you write your own function to detect rectangles. Your input would be the pixel data and your outputs would be something like the x,y locations of the rectangles.Show More ResponsesFirst of all, hough transformation can be used. just parametrize the representation for rectangle, but the parameter space is 4D. Second, line detection, followed by checking corner degree. In practice, I would use opencv's coutour fitting function to fit for quadrilateral, then check the angle. This works quite well.
