The goals of image compression:
To achieve image compression, there are two general types of compression schemes: lossy compression schemes and lossless compression schemes.
In the field of medical imaging, it is very important to maintain quality of the images being exchanged while minimizing the size of the images. This aspect is very important when considering which type of compression schemes is used when performing image compression.
- Reduce irrelevance and redundancy of the image data in order to be able to store or transmit data in an efficient form.
- The reduction in file size allows more images to be stored in a given amount of disk or memory space.
- It also reduces the time required for images to be sent over the Internet or downloaded from Web pages.
To achieve image compression, there are two general types of compression schemes: lossy compression schemes and lossless compression schemes.
- Lossy compression schemes: a compression scheme that does not encode all of the original data into the compression. Hence, the image that is reproduced is of similar but lesser quality than the original after decompression.
- Lossless compression schemes: a compression scheme that does encode all of the original data into the compression. Hence, the image that is reproduced is of the same quality than the original after decompression.
