Description: Ultrasound Speckle Reduction Using Coded Excitation and Pulse Compression
Ultrasound images are riddled with system dependent imperfections called speckle (multiplicative noise). In ultrasonic imaging, detection of small lesions could be difficult because the effects of speckle may mask the visibility of these small targets. Therefore, the purpose of this project is to decrease speckle while maintaining some of the key salient features in the image. Images of tissue-mimicking phantoms will be created using Field II [1-2] in MATLAB (Natick, MA). Image quality metrics such as speckle signal-to-noise ratio (sSNR) [3] and contrast-to-noise ratio (CNR) [4] will be used to quantify improvements in image quality after various despeckling filters have been applied.

Description: This paper analyses impact of using averaging filtering on quality of SAR images. These are commonly corrupted by
multiplicative complex correlated noise (speckle) and by additive white Gaussian noise. Methods presented in this
paper: multilook algorithm and averaging filters are examined in the context of additive white Gaussian noise reduction
and computational demands. In order to obtain high cross-range resolution of SAR images Map-Drift Autofocus
algorithm is also employed Platform: |

Description: LEE Filter for SAR Speckle reduction
im：SAR影像
w_size：窗口大小，奇数 3 5 7 9等
out_size：输出图像的大小，可以是 same 或者 full
NL：number of Looks，等效视数
bound：边缘扩展模式，分为 symmetric ， replicate , circular 。
flag：计算时是否包含中心像素，0为不包含，1为包含。
bound和flag主要是给im_mean_var用的 :)
im_ret：滤波结果
