Directly Rasterizing Straight Line by Calculating the Intersection Point [PDF]
Lecture Notes in Computer Science, 2005 In this paper, a method of line scan-conversion is presented by calculating the intersection point of straight line with the middle scan line of screen. With this method, the pixel’s screen coordinate of spatial line could also be obtained. Moreover, raster precision is exactly the same as that of Bresenham’s middle algorithm; and more than or at least

Extracting Palmprint ROI From Whole Hand Image Using Straight Line Clusters
IEEE Access, 2019 This paper proposes a novel method to extract a palmprint region of interest (ROI) from whole hand images using straight line clusters. The core idea of our method is that the fingers can be easily detected by straight line clusters due to the ...
