Image Enhancement for example, the removal of blurring.
Another example is increasing the effectiveness of the finger print, which can be achieved by using the histogram equalization of the image histogram.
Of course, to recognize the finger a set of other processing on the image need because in order to get a quick comparison with the database the result must be binary.
Image Enhancement can be done in order to improve the quality and resolution of the image for example in the below image, We use from edge detection.
Colorful Histogram Equalization
using colorful histogram equalization, the images that were made in low light can be improved.
Automatic Gray Level Images Segmentation
Auto-reading License Plate
image matching is one of the most widely used objects in artificial intelligence and machine vision that has been described in the "image matching " of this site.
Image Forgery Detection
Image forensic is called all processes that are used to detect manipulation in the image.
Frequency extraction from different vibrating object.
Radial distortion correction of lens (the usage are in fish eyes cameras)
Fusion of Images
Correction perspective distortion (application in all cameras during geometric corrections)
The background separation is done for various goals, such as detecting and tracking movement or extracting text from the image.
Delete the median shadow and nonlinear distortion of the scanned book
Delete distracting areas image
Sometimes it is necessary to remain only an integrated area of the image, for example, for traffic and driving tasks we just interested to know what happens in the street.
Placing a signature or watermark on the low significant bit (LSB) layer of the image to preserve the authority right of image and activate image forensic
Ellipse fitting has many applications such as face detection and round object recognition.
Elimination image magnification effects
After making each image larger (or zooming) due to the constraints of pixels, the block effects appear that due to the image resolution can be overcome this limitation by means of some methods.
