Poor image
Posted: Tue Jul 22, 2008 1:10 pmI have poor quality CCTV. How can image enhancement help?
Image enhancement can uncover information within the image that is not initially evident. Unfortunately CCTV images generally have low information content so any improvement is only marginal at best.
However the following simple enhancement techniques could be beneficial.
* Adjusting the brightness and contrast levels
* Applying sharpening or edge enhancing filters
* Increasing the colour saturation
* Removing noise
More sophisticated image enhancement systems are available, but again their effect is limited on low quality images.
