Edge Detection And Correction Algorithm For 3d Ct Images The normal direction of the bone contour in computed tomography (CT) images provides mportant anatomical information and can guide segmentation algorithms. Since various bones in CT images havedifferent sizes, and the intensity values of bone pixels are generally nonuniform and noisy, estimation of the normal direction using a single scale is not reliable. We propose a multiscale approach to...... Similar Editorial : by enterthezen. | Source : Science Lesson Plan
Simultaneous Despeckling & Compression Of Med Ultrasound Images A novel technique for despeckling the medical ultrasound images using lossy compression is presented. The logarithm of the input image is first transformed to the multiscale wavelet domain. It is then shown that the subband coefficients of the log transformed ultrasound image can be successfully modeled using the generalized Laplacian distribution. Based on this modeling, a simple adaptation of...... Source : Science Lesson Plan
