Discrete Browser is a web browser (like Internet Explorer) with special features which allow much greater privacy for your online surfing experience. Discrete Browser's Insta-Hide allows you to instantly hide the browser if, for example, someone unexpectantly walks in on you. Discrete Browser's visibility level can be ajusted from normal (opaque) to varying levels of transparency. This disguises the look of the browser and makes the displayed content more hidden from nosey eyes. Windows 2000 or Windows XP. Pewter Software -- Home Page..

function [g] = FFTPF1D (X,binsize, f, P) Discrete Fourier Transform Low/High Pass Filter. % This is a simply implement of such a filter for a given 1-D data. X: the array of you data, each data point is a bin of signal binsize: the bin size in your data data f: the cutoff of wave length, P: 1, or 0, true or false : true, low pass, which eliminating higher than f frequence signals, false, high pass, which eliminating lower than f frequence signals. It could be easily modified into 2-D version, or translated into R/S-language. Example: a=1:2:1000; b=sin(a) + sin(2.*a) + sin(0.1 .* a) + .

Y = DCTN(X) returns the discrete cosine transform (DCT) of X. X = IDCTN(Y) returns the inverse discrete cosine transform (IDCT) of Y. Y = DSTN(X) returns the discrete sine transform (DST) of X. X = IDSTN(Y) returns the inverse discrete sine transform (IDST) of Y. X and Y can be N-dimensional. D = DSTMTX(k) returns the k-by-k DST transform matrix. Enter "help dctn", "help dstn", "help idctn", "help idstn" and "help dstmtx" in the Matlab command window for complete information. Example ------- RGB = imread('autumn.tif'); I = rgb2gray(RGB); J = dstn(I); imshow(log(abs(J)),[]), colormap(jet), colorbar The commands below set values less than magnitude 10 in the DST matrix to zero, then reconstruct the image using the inverse DST.
