Abstract
Official abstract text for this publication.
A camera surveillance system having a camera malfunction function includes an entire feature extraction unit to extract each entire feature from an input image and a reference image; a block feature extraction unit to extract block features being features of each block from images after the block division of the input image and the reference image divided into blocks by a block division unit; and a malfunction determination unit to calculate a first variation between the entire features of the reference image and the entire features of the input image, and a second variation between the block features of the reference image and the block features of the input image, to determine a camera malfunction by using a threshold, and output information indicating a type of the camera malfunction for each block.
