Non-analytic object recognition using the Hough transform with the matching technique

P.-K. Ser, W.-C. Siu
1994 IEE Proceedings - Computers and digital Techniques  
By using the combination of the Hough and the contour sequence matching techniques, we suggest a new algorithm of scale and rotation invariant for pattern recognition.  ...  In order to enhance the performance of the Hough transform, we also suggest a new peak searching technique on the Hough space to achieve an accurate location of the detected objects.  ...  The advantage of the suggested rotation Hough transform is that it is suitable for the determination of the lengths of straight lines in an image.  ...

A Survey on Hough Transform, Theory, Techniques and Applications [article]

Allam Shehata Hassanein, Sherien Mohammad, Mohamed Sameer, and Mohammad Ehab Ragab
2015 arXiv   pre-print
What we care about here is emphasizing some of the most crucial milestones of the transform. We describe its variations elaborating on the basic ones such as the line and circle Hough transforms.  ...  For more than half a century, the Hough transform is ever-expanding for new frontiers. Thousands of research papers and numerous applications have evolved over the decades.  ...  For example in [61] , the FPGA is used to store the Hough parameters in its memory block. This approach is not only memory efficient but can also be used for both line and circle detection.  ...

2002 Lecture Notes in Computer Science  
Online processing of the data is necessary in order to select interesting events or sub-events (highlevel trigger), or to compress data efficiently be modeling techniques.  ...  Both require a fast parallel pattern recognition. Processing this data at a bandwidth of 10-20 GByte/s requires a massive parallel computing system.  ...  The information from the online pattern recognition can be used for data compression, to derive physical quantities (e.g. momentum, impact parameters etc.) for High-Level Trigger decisions and for online  ...
