A POSHE-Based Optimum Clip-Limit Contrast Enhancement Method for Ultrasonic Logging Images
Enabled by piezoceramic transducers, ultrasonic logging images often suffer from low contrast and indistinct local details, which makes it difficult to analyze and interpret geologic features in the images. In this work, we propose a novel partially overlapped sub-block histogram-equalization (POSHE...
