This paper introduces a correlation histogram method for analyzing the different components of depth-enhanced 3D video representations. Depth-enhanced 3D representations such as multi-view video plus depth consist of two components: video and depth map sequences. As depth maps represent the scene geometry, their characteristics differ from the video data. We present a comparative analysis that identifies...
Aims to provide general technicians who manage pects in production with a convenient way to recognize them, a novel method to classify insects by analyzing color histogram and GLCM (Gray-Level Co-occurrence Matrices) of wing images is proposed. The wing image of lepidopteran insect is preprocessed to get the ROI (Region of Interest); then the color image is first converted from RGB(Red-Green-Blue)...
Estimating printing source is applicable in many forensic situations. In this paper, we propose an electrophotographic printer identification scheme from its printed material, in which imperceptible halftone patterns are contained inherently. The halftone textures in each channel of CMYK domain are analyzed. We construct a histogram from angle values of linear features extracted by Hough transform...
In this paper, we propose a fast pattern matching algorithm based on normalized cross correlation (NCC) with centroid bounding to achieve very efficient search. The algorithm will calculate histogram around centroid within maximum circle with radius R. After dividing the image into blocks by R??R size, calculating the similarity between the color histograms of the image block and centroid around circle...
