For the distribution of skewness or outliers, the median is a better indicator to represent the trend of the data center.

construction. Mallat studies the discrete form of wavelet transform, and applies the corresponding algorithm to the decomposition and reconstruction of images, which lays a foundation for the subsequent wavelets image compression. In the 90 's, the research of image compression using wavelet has received unprecedented attention. This period is the time when the internet is booming, so how to adapt to the characteristics of the network image coding has been paid attention to. In 1993,
Q: Read the entire textbook quickly, list 5-10 questions you don't understand, and post it on your personal blog.
If the needs of users are too harsh, it is necessary to reduce the efficiency of software to meet them?
Does the team have to "program" and "test" clearly separate when doing engineering work?
Is it permissible to modify a part of the design on the way to the project? Or does it require that all designs be fixed and not changed before the project is started?
