    • PROBLEM TO BE SOLVED: To provide a feature detection device capable of rapidly detecting a feature. SOLUTION: An accumulation module accumulates a cumulative value of the luminance of each pixel included in one row to a row direction in parallel to all rows (step S4). An accordance processing module scans a plurality of scan windows to the row direction in parallel, calculates a light/shade difference of a pixel area based on a shape of a Haar feature, verifies accordance between the calculated light/shade difference of the pixel area and a light/shade difference of the Haar feature, and executes the processing of calculating the cumulative value q k that is a verification result of the accordance to the row direction in parallel. A strong discriminator module compares the cumulative value q k with a threshold T, and executes the processing of deciding that a face of a person is detected to the row direction in parallel when the cumulative value q k not smaller than the threshold T is detected.

    • 要解决的问题:提供能够快速检测特征的特征检测装置。 解决方案:累积模块将行中包含的每个像素的亮度的累积值累加到与所有行并行的行方向(步骤S4)。 一致处理模块并行地扫描多个扫描窗口到行方向,基于Haar特征的形状计算像素区域的亮/暗差,验证所计算的像素区域的光/阴差与 Haar特征的亮度/亮度差异,并且执行作为行方向的验证结果并行计算的累积值q SB> k 的处理。 强鉴别器模块将累积值q k 与阈值T进行比较,并且当累加值q 时执行决定人的脸部被并行地检测到行方向的处理, 检测不到阈值T的k 。 版权所有(C)2011,JPO&INPIT
