PIXEL-BY-PIXEL ESTIMATION OF SCENE MOTION IN VIDEO
video sequence image processing moving object detection tracking recurrent procedures reverse processing
2017/6/19
The paper considers the effectiveness of motion estimation in video using pixel-by-pixel recurrent algorithms. The algorithms use stochastic gradient decent to find inter-frame shifts of all pixels of...
Hierarchical Background Subtraction using Local Pixel Clustering
Hierarchical Background Subtraction Local Pixel Clustering
2013/7/17
We propose a robust hierarchical background subtraction technique which takes the spatial relations of neighboring pixels in a local region into account to detect objects in difficult conditions. Our ...
A PIXEL-WISE LOCAL INFORMATION-BASED BACKGROUND SUBTRACTION APPROACH
Background subtraction Gabor filters spatial feature vector Gaussian Mixture Model
2013/7/17
Background subtraction is a widely used method for moving object detection in computer vision. It is usually applied in video surveillance systems. There are two major kinds of background subtraction ...
A Visual Cryptographic Technique for Chromatic Images Using Multi-pixel Encoding Method
Visual Secret Sharing Halftoning Colour Model Information Security
2014/3/12
Visual cryptography is a secret sharing method that uses human eyes to decrypt the secret. Most visual cryptographic methods utilize the technique of pixel expansion, which causes the size of the shar...
