Check on defect - option specifies whether you want to check the images for defects. By default, this option is enabled.

Check on blockiness - the option defines, whether it is necessary to check pictures for existence of artifacts of compression of JPEG - a blockiness. The blockiness is defined by the greatest amount of gradients of brightness for extreme pixels of units 8x8. By default, this option is disable.

Check on bluring -the option defines, whether it is necessary to check pictures for too big blur of the image. Blur is calculated a gradient of the second derivative (which it is maximum on lines and edges) for the original image and its reduced options. Exact value is defined by method of the linear interpolation. By default, this option is disabled.
