Title:
オブジェクトの特徴差異を用いた複数のオブジェクトを含む動画像の画像認識方法及び該方法を使用するシステム
Document Type and Number:
Japanese Patent JP4806288
Kind Code:
B2
Abstract:
A characteristics-based image recognition method for recognizing objects in an image is implemented using an image sensor and a register. The image sensor has a plurality of pixel sensing elements. The method includes: setting a grayscale threshold value of the image; acquiring pixel values of each row sequentially in the image; identifying a background region and linear image segments of the objects in the image according to the grayscale threshold value; identifying the objects to which the linear image segments belong according to a spatial correlation between a newly detected linear image segment and a previously detected linear image segment; associating collected information of the linear image segments with the identified objects to which the linear image segments belong; and distinguishing the identified objects from each other based on solid, ring-shaped, long and short characteristics.
