Description: Recognition of visual patterns and characters are independent of position, size, and orientation in the visual field has been the goal of much recent research. The method presented in this paper meets all these condition. An off-line signature matching system which is based on Hu moment invariant method is presented here. Signature matching uses a four - steps process. In first step the scanned or captured color images are initially converted to grey scale. Second step performs normalization and digitization of the original signature. Noise reduction (also called “smoothing” or “noise filtering”) is one of the most important processes in image processing is performed in third step and then moment invariant vectors are obtained in the last step. Signature matching system is implemented using MATLAB and ability of the system can be increased by using additional features in the input data set. Platform: |

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.
