IP3 2019-Image Processing 2

This lot is generally related to image processing. Techniques are disclosed to provide a hierarchical shadow detection algorithm by performing pixel level classification by modeling the image as a reliable lattice (RL) and maximize the RL using an Expectation Maximization (EM) algorithm to determine whether a candidate region is a shadow region. Also disclosed is a Markov Random Field (MRF) model based pixel classification for effective and robust shadow detection under different illumination and brightness conditions. The technology may be implemented in image processing for feature detection, feature extraction, etc.
