چکیده

This paper presents a method that proposes the composition of the Map-Reduce algorithm and the Hough Transform method to research particular features of shape in the Big Data of images. We introduce the first formal translation of the Hough Transform method into the Map-Reduce pattern. The Hough transform is applied to one image or to several images in parallel. The context of the application of this method concerns Big Data that requires Map-Reduce functions to improve the processing time and the need of object detection in noisy pictures with the Hough Transform method.

Iris localization by means of adaptive thresholding and Circular Hough Transform

In this paper, a new iris localization method for mobile devices is presented. Our system uses both intensity and saturation threshold on the captured eye images to determine iris boundary and sclera area, respectively. Estimated iris boundary pixels which have been placed outside the sclera will be removed. The remaining pixels are mainly the boundary of iris inside the sclera. Then, circular ...

Fast Detection of Gpr Objects with Cross Correlation and Hough Transform

Abstract—A GPR object detection algorithm delivers a promising performance using the Hough transform through a high computational load. This paper presents a fast Hough-based algorithm. To reduce the parameter space of the Hough transform, first, two parameters for a reflection hyperbola were estimated using cross correlation between adjacent A-scans. Next, only a 1D Hough transform is necessar...

Coin Recognition Using Circular Hough Transform

This paper represents algorithm for recognition of the coins of different denomination. The proposed system first uses a canny edge detection to generate an edge map, then uses CHT (Circular Hough transform) to recognize the coins and further find the radii of them. Based on the radius of the coin, the coins of different denomination are classified. The experimental result shows that the Hough ...

Crop-row detection algorithm based on Random Hough Transformation

It is important to detect crop rows accurately for field navigation. In order to spray on line, a variable rate spray system should detect the crop center line accurately. Most existing detection algorithms are slow to detect crop rows because of the complicated calculation. The gradient-based Random Hough Transform algorithm could improve the calculation speed and reduce the computation effect...
