image compression makes the image smaller in order to fit a desired size. you literally compress the image and make it smaller in bit size.
It is the creation of digital image, typically from a physical scene. The term assumed to imply or include processing,compression, storage, printing, and display of such image.
because in fractal coding you save Coefficients of image blocks instead of values of block pixels. decoding starts from initial image and Coefficients applied on it. so the initial image can have any resolution
spinning image yes
Image processing is the method of processing data in the form of an image. Image processing is not just the processing of image but also the processing of any data as an image. It provides security.
1. Image acquisition 2. Image restoration/enhancement 3. Image segmentation 4. Image interpretation
compression ratio=uncompressed image size/compressed size
motivation of lossless image compression
No .... They are just Friends :]
Any type of compression will ideally reduce the size of an image. There are two types of compression which describe how they affect images:"Lossy" compressionThis type of compression reduces the size of the image by removing some data from it. This generally cause, effect the quality of the image, which mean it will reduce your image quality."Lossless" compressionThis type of compression reduces the size of the image by changing the way in which the data is stored. Therefore this type of compression will make no changes in your image.
Which compression type using in BMP image file? The BMP image file normally doesn't use any compression at all. This is why usually they are large files and are not used on the web.
Image Compression reduces the file size of an image without changing any part of the image. Image Editing involves changes to colour, addition or subtraction of element of and image that may or may not change the size of the image
Benefits of Image Compression 1. Reduce the size of the image to be transmitted 2. This will definetly speed-up the processing time 3. Optimal use of Storage space 4. Optimal utilization of transmission media By Victor
Image compression is used to reduce the size of the stored data. This is done either for storage purposes or to improve transfer times.

It is the creation of digital image, typically from a physical scene. The term assumed to imply or include processing,compression, storage, printing, and display of such image.
Slant transform is used in image compression techniques.
In general, the more you compress the less you enhance.
