I believe that in the face of procedural problems involving geometric operations, there is no need to draft a direct strike out the correct code of the great God is present, of course I am not.Recently encountered a practical problem, need to use the knowledge of trigonometric functions learned in junior high school to solve, the problem is described by trigonometric function is in a right triangle, known as a angle α angle, and the angle α of the adjacent e
ScrollView white edge problem, scrollview white edge
In ScrollView used by Android development, when it is compatible with a relatively low version (for example, 14), there will be ugly white edges, if the xml layout file is used, set android: fadingEdge of ScrollView to none to cancel the white edge.
In java code:

SVM-Based Edge persistence filtering algorithm-SVM for edge-preserving Filtering
Qingxiong Yang shengnan Wang Narendra Ahuja 1. Introduction: In this article, the author proposes a method similar to bilateralFiltering. The normalized convolution kernel of bilateral filtering is determined by the distance between the center pixel and Its pixel and the gray-scale change range. The distance and gray-scale chan

On the internet to see someone said Avplay can play streaming media, then take over to use, and found that anyway it is to the MP3 cache after the completion of the play, the audio long to wait, for the M4A format is better, MP3 is not, and this experience is very poor. So on the Internet to collect methods, and found the Freestreamer library can achieve edge caching while playing MP3 files, online data is relatively small. Here's a general summary. M

In the factory method, you are responsible for the creation of specific class objects, which can be called a simple factory model. A factory is responsible for the creation of all products, different products are created by inputting necessary parameters to the factory. Generally, the created products are related and inherited from an
Previous notes, finishingWEBRTC uses UDP transport by default, but it can also be transmitted over TCP.With TCP transport, servers such as Turnserver,licode,janus and servers are required.1. If you use Turnserver, you only need the client to keep the relaytcp type of candidate, the others are discarded.2. If you are using a server such as Licode,janus, TCP is not supported by default.Because they are used at the bottom of the Libnice open-source Ice library, Libnice supports TCP in newer version
