摘要： A local feature amount calculating device includes a local feature amount calculating unit that acquires a local feature amount of a feature point for each pixel by giving a vote of a strength of the direction of a pixel, which is calculated by a direction strength calculating unit, to a vote cell to which a pixel of interest belongs out of vote cells of a rotated vote cell pattern that is acquired by rotating a reference vote cell pattern by an angle corresponding to a main axis direction along a corrected edge gradient direction that is acquired by correcting an edge gradient direction of the pixel that is calculated by a direction strength calculating unit in accordance with the main axis direction.

摘要： A bit code converter transforms a learning feature vector using a transformation matrix updated by a transformation matrix update unit, and converts the transformed learning feature vector into a bit code. When the transformation matrix update unit substitutes a substitution candidate for an element of the transformation matrix, a cost function calculator fixes the substitution candidate that minimizes a cost function as the element. The transformation matrix update unit selects the element while sequentially changing the elements, and the cost function calculator fixes the selected element every time the transformation matrix update unit selects the element, thereby finally fixing the optimum transformation matrix. A substitution candidate specifying unit specifies the substitution candidate such that a speed of transformation processing that the bit code converter performs using the transformation matrix using the transformation matrix is enhanced based on a constraint condition stored in a constraint condition storage unit.
摘要翻译：位代码转换器使用由变换矩阵更新单元更新的变换矩阵来变换学习特征向量，并将变换后的学习特征向量转换为位代码。当变换矩阵更新单元将替代候选替换为变换矩阵的元素时，成本函数计算器将成本函数最小化的替代候选者固定为元素。变换矩阵更新单元在顺序地改变元素的同时选择元素，并且每当变换矩阵更新单元选择元素时，成本函数计算器固定所选择的元素，从而最终确定最佳变换矩阵。替代候选指定单元指定替换候选，使得基于存储在约束条件存储单元中的约束条件来增强使用变换矩阵的比特码转换器使用变换矩阵执行的变换处理的速度。
