<p>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.</p> |
