Abstract

An image-based object counting method includes rasterizing a counting line in an image into counting line pixels; determining two points on a trajectory line included in the image, as target pixels; determining, from the counting line pixels, corresponding pixels that corresponds to the target pixels; determining whether the counting line intersects with the trajectory line based on the target pixels and the corresponding pixels; and determining the number of one or more trajectory lines including the trajectory line that intersect with the counting line as the number of objects that pass through the counting line.
