This function implements multivariant Gaussian kernel regression and smoothing. A few examples show how it can be used to smooth 3-d noisy images with missing data.For tutorial purpose, the function is implemented in the simplest form. Therefore, it is particularly suitable for beginners to learn...

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...

Kernel regression is a power full tool for smoothing, image and signal processing, etc. However, it is computationally expensive when it is extented for multivariant cases. The efficiency can be improved by only using neighbors within the effective range arond a regression point. To improve the...

This is a companion to Matlab's Statistics toolbox ksdensity function and Philipp Berens' CircStat toolbox.The difference with Matlab's ksdensity function is that this function is adaped to circular data, such as wind orientation. Using Matlab's function will give biased values at the extremities...

A common technique for removing noise from images is by blur-ring them with a weighted mean or a Gaussian filter. Through theseprocesses noise reduction is achieved, but unfortunately, valuableinformation is lost and the details of object boundaries aredeformed. A solution to this problem,...

Subspace learning based face recognition methods have attracted many researchersd-deOao interests in recent years. In thispaper, a novel Laplacian Smoothing Transform (LST) is proposed to transform an image into a sequence, by which low frequencyfeatures of an image can be easily extracted for a...

A contour of a 2D region is defined by an ordered set of points where the neighboring elements contain the neighboring points. Such representation can be obtained with many techniques such as boundary tracing and chain codes. (In a simple 2D point set or a curve the points do not have to lie in a...
