Discussions on Image Format Comparisons
- Several commonly used image compression algorithms
Image compression is the process of reducing the file size while retaining the same or most of the data. The principle is to eliminate unnecessary data or reorganize the data in a more efficient forma
- What advantages does WebP have over PNG and JPG?
Currently, images still account for a significant portion of network traffic, especially on mobile devices. Therefore, reducing image size without compromising visual quality is crucial for saving ban
- What are the commonly used image compression methods in image processing?
So here comes the question, there is a most basic question, What is an image? The images we encounter nowadays are mostly digital images (so we won’t discuss analog images anymore). What is a digital
- Resolution ≠ Image Quality? What is the Principle of Image Compression at Constant Resolution?
Suppose we zoom in on an image and look at just eight pixels, it would look like this.In a computer, this color block should be recorded like this (hypothetically):"Position 1: red, Position 2: o
- Principles of Image Compression (with a small amount of linear algebra popularization)
Wavelet Basis-Based Compression AlgorithmsAll compression algorithms mentioned here are lossy compressions.It is believed that everyone understands that images are represented in computers as pixel ma
