Sine Cosine Tangent

The function is much faster than Matlab's native (dct, idct, dct2, idct2). It also allows N-D (multidimensional) input.Example:x=randn(100,200,300);y=mirt_dctn(x); % forward DCTx=mirt_idctn(y); % inverse DCTFind more at my home page:http://www.bme.ogi.edu/~myronEnjoy and comment below if you like...

Y = RESIZE(X,NEWSIZE) resizes input array X using a DCT (discrete cosine transform) method. X can be any array of any size. Output Y is of size NEWSIZE.Input and output formats: Y has the same class as X.As an example, if you want to multiply the size of an RGB image by a factor N, use the...

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...

Gabor-function convolution masks are increasingly used in image processing and computer vision. This function simply computes the cosine and sine masks for a given width, period and orientation. The masks returned are properly normalised. It is not highly optimised - e.g. the symmetries are not...
