| Abstract: | In order to solve the problem of appearing the phase jitter phenomenon on the television logging image,a method of detecting the phase jitter logging image is proposed,which is based on correlative feature.The correlative feature of ultrasound image logging between adjacent rows is used to automatically search the jumping position and phase difference,then the image according to the jumping position and phase difference cyclically moved,and ultimately the goal of correcting the image is achieved.The experim... |
