Some preliminary codes for a number of papers are provided below. The codes may not be properly trimmed for performance and may look a little messy sometimes. If faced with any problem, kindly send me your comments.
1) Multiresolution Based Gaussian Mixture Model for Background Suppression: The codes are provided in Matlab. The simple Viptraffic sequence from Matlab is used for testing. It can be simply replaced with any other avi file. The Matlab file name: wavGMM.m.
Kindly cite the following paper if you use the codes for publications.
Mukherjee, D.; Wu, Q.M.J.; Nguyen, T.M., "Multiresolution Based Gaussian Mixture Model for Background Suppression," IEEE Transactions on Image Processing, 22(12), pp. 5022 – 5035, 2013.
2) Gaussian Mixture Model with Advanced Distance Measure based on Support Weights and Histogram of Gradients for Background Suppression: The codes are provided in Matlab. Matlab codes do not go well with simple loop operations. To avoid loops, I had to use a lot of indexing and matrix manipulation. However, the codes are still slow. If you manage to improve the speed, kindly share with me and I'll upload the better version with your name.
The Matlab file name: sptWtGradHistGMM.m.
Kindly cite the following paper if you use the codes for publications.
Mukherjee, D.; Wu, Q.M.J.; Nguyen, T.M., "Gaussian Mixture Model with Advanced Distance Measure based on Support Weights and Histogram of Gradients for Background Suppression," IEEE Transactions on Industrial Informatics, 10(2), pp. 1086 - 1096, 2014.
3) Motion Segmentation Based on 3D Histogram and Temporal Mode Selection: This is a pretty simple code written in Matlab. File name: hist3DMotion.m. It is important to mention here that the detection is unimodal.
Kindly cite the following paper if you use the codes for publications.
