I am so lazy in the middle that I haven't written a blog for a long time. Today I have studied Android ListView asynchronous image loading and image memory caching for several days. Hey. Android applications often need to handle image loading issues. Because images are generally stored on the server and need to be loaded online, this is a time-consuming process.

Previously, when I was doing image processing experiments, I often used Lena images as the processing objects. At that time, I often used the photographer's images. At that time, I often asked myself why I used these images? Why? Why are they used for standard test images? Why are these images used in teaching materials as examples? After reading "playmates" accidentally entered the academic circle in the squirrel meeting, I finally stole it. This doc

In Android development, we often encounter OOM exceptions caused by too many images or improper operations. Sometimes, although this problem is solved, it may affect the running efficiency of the program, for example: during the process of sliding the scroll bar quickly, our program is still loading images on the server, which gives users an extremely bad experience. In fact, there are a lot of explanations on asynchronous loading and caching of images on the network, but writing a program in th

Stretching, shrinkage, distortion, and rotation are geometric transformations of images. These transformations are widely applied in 3D vision technology, and include affine transformation and perspective transformation. Generally, a single-application modeling method is used for affine transformation. cvwarpaffine is used for dense ing, and cvtransform is used for sparse ing. The ry transform can convert a rectangle into a parallelogram. It can flatten the side of the rectangle But must keep th
