Abstract
An object sampling method is applied to an image analysis apparatus with an image receiver and an operation processor. The image receiver acquires an image stream. The object sampling method includes transforming color space of at least one surveillance image in the image stream, computing saturation and gradient of specific pixels within the at least one surveillance image, setting a bonding box within the at least one surveillance image, and computing a background score relevant to the saturation and value of all pixels in the bonding box, and comparing the background score with a first sampling condition so as to determine whether the at least one surveillance image is applicable for the image analysis apparatus via a comparison result of comparing the foreground score with the first sampling condition.
