To provide a method for recognizing an image containing a plurality of objects, capable of reducing the probability of wrong determination resulted from that the difference between two images is difficult to identify.
The image recognition method for a dynamic image containing a plurality of objects using the difference in characteristics of the objects uses an image sensor. The method includes: (A) setting a threshold of brightness level of the image; (B) acquiring pixel values of each row sequentially in the image; (C) identifying a background area according to the threshold; (D) identifying the objects to which linear image segments belong according to a spatial correlation between two adjacent rows; (E) collecting accumulated information of the linear image segments for each identified object; (F) determining the characteristic attribute of each object; and (G) recognizing it as any one characteristic attribute of solid, hollow, long and short characteristics.
