Software Downloads for "Canny Edge"

CORNER works by the following step: 1. Apply the Canny edge detector to the grey level image and obtain a binary edge-map. 2. Extract the edge contours from the edge-map, fill the gaps in the contours. 3. Compute curvature at a low scale for each contour to retain all true corners.All of the curvature local maxima are considered as initial corner candidates. 4. Initial corner candidates are compared using an adaptive local threshold to remove the round corners. 5. The angles of corner candidates are evaluated to eliminate any false corners due to quantization noise and trivial details.

1. Find the edge image using the Canny edge detector. 2. Extract edges (curves) from the edge image: 2a. fill gaps if they are within a range and select long edges, 2b. find T-junctions and mark them as T-corners. 2c. obtain the `status' of each selected edge ${Gamma}$ as either `loop' or `line'. 3. Smooth ${Gamma}$ using a small width Gaussian kernel in order to remove quantization noises and trivial details. This small scale Gaussian smoothing also offers good localization of corners. 4. Select significant points on the smoothed curve using scale evolution technique.

At each point of the smoothed curve ${Gamma_s}$, compute three discrete curvatures following the CPDA technique using three chords of different lengths.

This application can be used for magnifying (enlarging) digital images, extracting edges from an image with sobel and canny edge detector or applying other filters as well. There is also a guide (documentation) to digital image magnification & edge detection

It was my course project for Machine Vision, so do not expect something quite professional. I think it performs quite nicely already, so I don't think any of you will have any problems. It has quite a description in the beginning of the code, also suitable for help CannyEdgeDetector usage. Some methods and usages may not be preferably feasible, but they had to be included in the program, in order to provide the code working just like it is told in the original paper of Canny's. So it is quite suitable for also gaining the understanding of the concept, I suppose.

I built this under Windows with VC 2005 & R2007A, but there is nothing platform or compiler specific about it..

Phase information is used for matching the input imagery with the template. Both the images are filtered with canny edge detector. The timing efficiency is introduced by implementing skipping steps while doing correlation. The advantage of Phase based correlation technique is that it shows good response against shift/brightness variation and noise addition i.e. salt & pepper/Gaussian noise [1,2]. Templates includes small portion of cropped from input imagery with gaussian noise introduced in them.

Carries out Gaussian smoothing followed by differencing as a way of estimating the gradients of a grey-level image in the X and Y directions. This is the initial stage of the well-known Canny edge detector, but the gradients can be used for many other applications. The function offers independent control of the smoothing parameters. Particular care is taken of how pixels close to the image boundaries are treated. By default, the output gradient arrays are smaller than the image so that only valid values need be computed, but an option allows them to be the same size as the image.

Interesting things happen at the boundary between order and chaos, where the qualities of both states are evident. There is enough order to retain information, and enough chaos to provide variety. Many complex dynamic systems, including life itself, seem to naturally evolve towards this "edge of chaos", where adaptation, problem solving, and evolution by mutation and selection are all exhibited. A good way to explore this interesting phenomenon is to study a famous cellular automaton called "Conway's Game of Life" which inhabits the edge of chaos region.
