ABSTRACT:
The present invention provides methods, systems and a machine readable medium including machine readable code for identifying an ill-exposed image. An image including a first image block is received. The luminance data and the texture energy data associated with the first image block are assessed. A determination is made regarding whether the received image is an ill-exposed image based on the assessment of the luminance data and the assessment of the texture energy data associated with the first image block.
