2021?5?1? Index Terms—Semantic line detection Hough transform
The Hough transform (HT) named after Paul Hough who patented the method in 1962
We will explore the application of Sobel and Canny edge detection techniques. The next section introduces the Hough transform used for the detection of
These lines separate regions with different grey levels. • Edge detection is often used as preprocessing to Hough preprocessing to Hough transform. INF 4300.
The algorithm is ideally suited for real-time applications with a fixed amount of available processing time since voting and line detection is in- terleaved.

Hierarchical Hough Transform. 1.Introduction. Edge detection is one of the most frequent and important tasks of image processing. Line detection plays major.
Hough Transform is a voting technique that can be used to answer all of these questions. Main idea: 1. Record vote for each possible line on which each edge
Criteria for a good edge detector: – Good detection: the optimal detector should find all real edges ignoring noise or other artifacts – Good localization
In this context the objective of this work was the implementation evaluation and comparison of selected optimal edge detectors and the HOUGH transform
