Multi-scale edge detection with bilateral filtering in spiral architecture
Qimei Hu,Xiangjian He,Jun Zhou +2 more
TL;DR: In this article, the edge detection algorithm with the application of a bilateral filter in Gaussian form in Spiral Architecture is presented, where edge maps of the original image and its successively smoothed versions are used to produce the final edge map.

Binarization method based on evolution equation for document images produced by cameras
Yan Wang,Chuangjiang He +1 more
TL;DR: An evolution equation-based binarization method for document images produced by cameras that is controlled by a global force and a local force, both of which have opposite sign inside and outside the object of interests in the original image.
