动态加载图像算法的视频播放器的实现

在计算机与互联网高速发展的今天，视频播放器已经成为每台计算机终端必不可少的应用。现在的视频播放器通常指能播放以数字信号形式存储的视频的软件，种类繁多，功能强大，能够支持主流的多媒体格式，具有多种强大的解码方式，播放效果清晰流畅。但是大多数视频播放器并不开源，不支持深层的用户自定义操作，功能仅仅局限于播放，并且播放效果单一，对于视频处理并未有涉及，部分播放器在音视频同步问题和进度条跳转问题上还存在缺陷。本文基于Qt平台设计出一款既能满足普通播放需求，又可以加载用户自定义图像算法以实现不同的播放效果的播放器控件，具有单帧跳转、加载图像算法播放等视频播放功能，同时具有保存帧序、视频算法处理等视频处理功能。 With the development of computer science and Internet, video player has become an indispensa-ble application of each computer terminal. Most player usually play video with storage in the form of digital signal. With the large variety, powerful function, players can be able to support the mainstream multimedia formats and have many powerful ways of decoding. But, most of them are not open source, and don’t support the deep user-defined operation, and even have defects in Audio & Video synchronization and skip on progress. This paper designed a Qt-based player, which not only meets the demand of normal play but also can load user-defined image algorithm. It has jumping single frame and loading image algorithm and other video playback functions, and it also has saving frame sequence, processing video and other video processing functions.

Research on Aerobics Movement Choreography Based on Embedded Network Technology

Embedded Internet has preset functions and strong adaptability, which can be used in household appliances, medical equipment, and industrial machinery and so on. Through the method of embedded network, it completely changed the way of people live. In this paper we use clustering algorithm to improve the embedded network system, and use JSP technology to enhance the real-time and interactive of system, develop the aerobics visualization movement system, which realizes the interactive action between teachers and students. In order to test the performance of the system, we use AMBE-2000 as communication module to test the video compression and processing functions of embedded system. The results show that the compression ratio is big, the flow is small, and compression time is short. It is a stable and reliable network system. It provides a new method for embedded computer system in sports teaching.

Image Recognition System using Geometric Matching and Contour Detection

Image recognition plays an important role in a wide range of applications from biomedical imaging and security systems to scene surveillance and many other fields. This document presents the representation of the recognition of two images through the process of geometric comparison. The geometric comparison is performed by comparing the image with a template through the processes of edge detection, scaling, contour matching and RGB to grayscale conversion. The software utilized is NI vision which is one of applications of the National Instrument’s LabVIEW, used for the image and video processing functions.

System architecture for a multi-media enabled mobile terminal

A system architecture for mobile terminals is proposed, in which the signal processing for the cellular communications channel and the associated protocol stack processing are implemented independent of the application system, which handles audio and video processing functions and the user interface. This approach enables the use of open operating systems for the application system and the integration of connectivity communication pipes into the system, while maintaining the integrity and huge investment in the protocol stack software of the cellular subsystem. High speed digital serial links are used to connect the processing subsystems and the video peripherals. This improves the modularity of the solution and gives the equipment manufacturers increased flexibility.
