Image compression is used to reduce the size of the stored data. This is done either for storage purposes or to improve transfer times.

Which compression type using in BMP image file?
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.
How to calculate Compression ratio for an image?
compression ratio=uncompressed image size/compressed size
What is the need for compression?
motivation of lossless image compression
Why you are gotng to image compression?
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.
What has the author Arto Kaarna written?
Arto Kaarna has written: 'Multispectral image compression using the wavelet transform' -- subject(s): Image processing, Wavelets (Mathematics)
How does the quality of a sound or image file relate to its file size?
Smaller the size, more information is lost due to compression and therefore the quality gets lost. Smart compression techniques like mp3 or jpeg are using assumptions about the intended use of the image/sound to minimize compression losses in the relevant domain.
TIFF files can be edited and resaved without compression loss?
Yes, provided that they are not using a lossy compression like jpeg to store the image data. This should be configurable in the save dialogue.
How does compression effect images?
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.
Difference between image compression and image editing?
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
What compression formats are used for image?
Compression methods are used for images compression and most common compressions are JPEG which is lossy (you can lost some details or quality of image), LZW which is lossless, RLE and ZIP also lossless compressions.
What is a jpg files?
it's an image file on your computer. when it comes to pictures, there also .jpegs and .bins
What is the need for image compression?
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
