repeating x-ray radiographs, as a common problem in radiology units, represent additional, non-billable costs due to increased film, chemistry, and equipment use as well as increased personnel time. furthermore, patients receive additional radiation exposure from repetitions and must remain on the premises until the second exam is completed. compounding the overt negative financial impact on th...

Image enhancement is a primary need for the recognition of different biometrics in biometric-based identification systems. The recognition-rate of a biometric system depends heavily upon the quality of the input biometric given to the system. In this paper, a novel hybrid Fuzzy model (IEHFS) is proposed to improve the visual quality of iris images. The experimental results based on calculating ...

In image processing, image enhancement is used to improve the image quality through a broad range of techniques such as contrast enhancement, color enhancement, dynamic range expansion and edge emphasis and so on. In consumer electronics, many histogram equalization based methods have been used in recent years. Many of these methods are complicated to implement and also some method will produce...
