image compression using btc algorithm. matlab program. This function accepts an image(color or gray) and compresses it using the block truncation coding.
Quad Tree Bit Plane Compression.
A program to compress images. Qbit is an image viewer that loads and saves it s own imge format as well
as loading various Sun Raster File, Targa and Bitmap files.
Here s the code! Too many people ask for this
Using this code you can save an image item as a jpeg image, specifying the quality of it. Jpeg quality is the same as compression so the lower the quality, the smaller the file size. It s simple to use
A general technique for the recovery of signi cant
image features is presented. The technique is based on
the mean shift algorithm, a simple nonparametric pro-
cedure for estimating density gradients. Drawbacks of
the current methods (including robust clustering) are
avoided. Feature space of any nature can be processed,
and as an example, color image segmentation is dis-
cussed. The segmentation is completely autonomous,
only its class is chosen by the user. Thus, the same
program can produce a high quality edge image, or pro-
vide, by extracting all the signi cant colors, a prepro-
cessor for content-based query systems. A 512 512
color image is analyzed in less than 10 seconds on a
standard workstation. Gray level images are handled
as color images having only the lightness coordinate
wavelets are used extensively in signal and image processing,Medicine, Finance, Radar, Sonar, Geology
and many other varied fields. They are usually presented in mathematical formulae, but can actually be
understood in terms of simple comparisons with your data.
