A Local Thresholding Algorithm for Image Segmentation by Using Gradient Orientation Histogram

This paper proposes a new local thresholding method to further explore the relationship between gradients and image patterns. In most studies, the image gradient histogram is simply divided into <i>K</i> bins that have the same intervals in angular space. This kind of empirical approaches may not fu...
