Stereo Vision for 3D Measurement in Robot Systems

Journal of Engineering and Sustainable Development, 2013
The major obstacle in the application of stereo vision to extract 3D information is the error in disparity map and highly computational cost at conventional computers.

A Vision-Based Procedure with Subpixel Resolution for Motion Estimation

Sensors
Vision-based motion estimation for structural systems has attracted significant interest in recent years. As the design of robust algorithms to accurately estimate motion still represents a challenge, a multi-step framework is proposed to deal with both ...

Motion estimation algorithm using 2 bit-depth pixel and fuzzy quantization

Tongxin xuebao, 2013
A motion estimation algorithm was proposed using 2 bit-depth pixels. The reduction of pixel depth was first formalized by two successive steps, namely interval partitioning and interva mapping.

Modified Three-Step Search Block Matching Motion Estimation and Weighted Finite Automata based Fractal Video Compression

International Journal of Interactive Multimedia and Artificial Intelligence, 2017
The major challenge with fractal image/video coding technique is that, it requires more encoding time. Therefore, how to reduce the encoding time is the research component remains in the fractal coding.

Block Matching for Object Tracking

, 2003
Models which describe road traffic patterns can be helpful in detection and/or prevention of uncommon and dangerous situations. Such models can be built by the use of motion detection algorithms applied to video data.

Evaluating Blocking Biases in Entity Matching

2024 IEEE International Conference on Big Data (BigData)
Entity Matching (EM) is crucial for identifying equivalent data entities across different sources, a task that becomes increasingly challenging with the growth and heterogeneity of data. Blocking techniques, which reduce the computational complexity of EM, play a vital role in making this process scalable.

Covariance Estimation for SAD Block Matching [PDF]

, 2007
The estimation of a patch position in an image is a long established but still relevant topic with many applications, e.g. pose estimation and tracking in image sequences. In most systems the position estimate needs to be fused with other estimates, and hence, covariance information is required to weight the different estimates in the right way.

Integral Images Revolutions: Block Matching

, 2013
The integral image representation permits to evaluate the sum of image values over rectangular regions of the image with four operations, regardless of the size of the region.
