What are the 2 methods of compression?
There are two types of compression: lossless and lossy.
How 2d DCT can be used for image compression?
DCT is used in the JPEG image compression algorithm. The input image is divided into 8-by-8 or 16-by-16 blocks, and the two-dimensional DCT is computed for each block. The DCT coefficients are then quantized, coded, and transmitted.
What there is a need for compression of images?
The objective of image compression is to reduce irrelevance and redundancy of the image data to be able to store or transmit data in an efficient form. It is concerned with minimizing the number of bits required to represent an image. Image compression may be lossy or lossless.
What are the two different compression you can choose when enhancing your image?
You can choose two types of compression when optimizing your images: lossy and lossless compression. There are pros and cons to both, and you, as a website owner, should evaluate both before making a decision.
