Title:
特徴抽出装置、特徴抽出方法、特徴抽出プログラム、および画像処理装置
Document Type and Number:
Japanese Patent JP5789751
Kind Code:
B2
Abstract:
Provided is a feature extraction device including a sub region setting unit (433) which sets a plurality of sub regions with respect to a pixel of interest, and a binary pattern generation unit (434) which generates a local binary pattern indicating pixel value comparison results relative to each sub region with respect to each pixel of interest. The sub region setting unit (433) sets (436) a region constituted by a plurality of pixels including a pixel separated from the pixel of interest as a sub region, and the binary pattern generation unit (434) calculates (437) a representative value for each sub region and generates (439) a local binary pattern indicating whether or not the difference (438) between the representative value and the value of the pixel of interest is equal to or larger than a predetermined threshold value.
