Our nation is a vast country where the deployment of the hospital is scattered, while medical level also have significant and regional differences, especially in rural and remote areas, so it is necessary to develop the remote medical service and technology. However, the bandwidth of communication network cannot be capable of increasing unrestrainedly. This needs

In the network technology and electronic technology increasingly mature, network camera also has rapid development, and has an alternative to “Image Sensor+capture card” traditional image capture mode trend. Also, low-cost high-performance network camera in the automatic measurements, equipment testing, security monitoring and other industrial measurement has a increasing demand. However, the current domestic network camera

SAR images get wide application and rapid development because they can be obtained any-time, any-weather and with high resolution. Since each SAR image inevitably contains coherent speckle noise, the relationship between adjacent pixels reduced severely, and speckle noise is the key issue which restricts SAR image compression.Due to the SAR coherent imaging characteristics, the images

Wavelet transform has been broadly used in digital signal processing applications as an important time-frequency transform. It has a perfect performance on both local time and frequency domain, so it is an effective analytical method. This dissertation put emphasis on wavelet transform’s application to image de-noising and compression.First of all know the wavelet transformation, the
