We introduce the adaptive speckle reducing anisotropic diffusion(SRAD) that uses wavelet for enhancement of medical ultrasound images. This method first modifies coarse-to-fine classification to… (More)
In this paper, we introduce the modified speckle reducing anisotropic diffusion(SRAD) that uses wavelet decomposition for speckle reduction in medical ultrasound(US) images. As a first step of our… (More)
introduce speckle noise reduction and active contour model detection in the medical ultrasound images region of cancer or tumor effectively. Medical ultrasound image has called noise of the speckle… (More)
system is easily to acquire no distortion image sequences without any preprocessing. Robust feature detection method is also described for VSLAM of a service robot in indoor environment. This method… (More)
In CMOS image sensor, 1/f noise is determined by width and length of gate at the circuit. Reducing the 1/f noise, a correlative multi sampling and an autocorrelation method have been used, mainly.… (More)
