MQTT(连接、订阅、发布、断开)示例
【实例简介】MQTT(消息队列遥测传输)是ISO 标准(ISO/IEC PRF 20922)下基于发布/订阅范式的消息协议。它工作在 TCP/IP协议族上,是为硬件性能低下的远程设备以及网络状况糟糕的情况下而设计的发布/订阅型消息协议,此示例主要使用paho-mqtt.js 连接mqtt服务端,并实现消息的订阅发布

实现图像的无损压缩
该程序主要实现图像的无损压缩,具体算法包括:
(1)整数小波变换+SPIHT无损压缩
其中整数小波可以采用JPEG2000提供的5-3小波,也可以采用S+P变换,本程序均已给出。
(2)DPCM+算术编码
DPCM采用的是JPEG中采用的方法;
(3)JPEG-LS标准
JPEG-LS的无损压缩性能非常好,超过JPEG2000。(The program mainly realize lossless image compression, the specific algorithm include: (1) integer wavelet transform SPIHT Integer Wavelet lossless compression which can be used to provide the 5-3 wavelet JPEG2000, can also adopt the S P transform, the procedures are given. (2) DPCM arithmetic coding DPCM is used in JPEG methodology (3) JPEG-LS standard JPEG-LS lossless compression of very good performance, more than JPEG2000.)

DIC
通过数字图像相关的方法计算两幅图像之间的位移,计算时间较长,是最基础的DIC,没有优化。(Digital image correlation method to calculate the displacement between the two images, the time is longer, is the most basic DIC, no optimization.)
