Why canny? The Canny edge detector is an edge detection operator that uses a multi-stage algorithm to detect a wide range of edges in images. It was developed by John F. Canny in 1986. Canny also produced a computational theory of edge detection explaining why the technique works. WHY CNN IN IMAGE PRO? In machine learning , a convolutional neural network ( CNN , or ConvNet ) is a class of deep, feed- forward artificial neural networks that has successfully been applied to analyzing visual imagery. CNNs use a variation of multilayer perceptrons designed to require minimal preprocessing . [1] They are also known as shift invariant or space invariant artificial neural networks ( SIANN ), based on their shared-weights architecture and translation invariance characteristics. [2] [3] CNN is uised in Image processing for recongnistion on images,video ,pattern ,speech , natural by training

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
