The function may be a property of a document containing the grayscale image, such as the size of the document. In this case, pixels outside of the document boundaries are removed from the histogram during the updating of the histogram....
Grayscale ImageHardware ArchitectureFPGASoCA novel histogram generation hardware architecture, which can develop histogram for all types of grayscale images of size (256 x 256), is presented in this paper. The histogram produced from the proposed hardware gives exactly the same information as ...
1. A method of modifying the histogram of a grayscale image to improve contrast, comprising: extracting black connected components from the grayscale image that touch at least one of the margins of the grayscale image; computing the histogram of the portion of the grayscale image covered by ...
Functions : 1) hist_curve : returns histogram of an image drawn as curves 2) hist_lines : return histogram of an image drawn as bins ( only for grayscale images ) Usage : python hist.py <image_file> Abid Rahman 3/14/12 debug Gary Bradski ...

SIFT :scale invariant feature transform HOG:histogram of oriented gradients 这两种方法都是基于图像中梯度的方向直方图的特征提取方法。 1. SIFT 特征 实现方法: SIFT 特征通常与使用SIFT检测器得到的感兴趣点一起使用。这些感兴趣点与一个特定的方向和尺度(scale)相关联。通常是在对一个图像中的方形区域通过相应...
Image can be either 2D or 3D, grayscale or color. For color images, the result is the concatenation of the histogram computed for each band. If no output is requested, the histogram is plotted on the current axis. Several options can be applied, like min and max levels to consider, ...
