Multi-scale edge detection of 3D image based on adaptive threshold;

3D image compression of the 3D laser scan measure system;

3D Image of Nano-Second Laser Flash Photolysis Based on Origin Software

A general method of drawing three-dimensional image for the electron probability angle distribution in the hydrogen atom is given;and a mistake from a textbook is corrected.

This article summarizes the spatial domain,frequency domain and mixed edge detection methods in two-dimensional images,focuses on the super-wavelet edge detection method and its advantages,and then summarizes and compares them with the current edge detection methods in three-dimensional images and gives the direction of development.
