In the field of digital photogrammetry, it is very important to enhance the image resolution. By enhancement, a clearer image with higher resolution is produced. So far, the enhancement technique is widely applied in various photogrammetric images. However, because of the restriction of the CCD sensor itself, the number of pixels on the sensor isn’t much enough in some case. The image quality i...

Finger print recognition technique is one of the challenging tasks in biometric security system. Apart from the Automatic Fingerprint Identification system (AFPIS) the offline and latent finger prints are still suffering in quality issue, hence, there is need for image enhancement. Now, a day’s various filters were used for fingerprint enhancement, but no one of them has proved 100% quality on ...

Video enhancement plays an important role in various video applications. It includes.1) to achieve high intra frame quality of the entire picture where multiple regions-of-interest (ROIs) can be adaptively and its well simultaneously enhanced and 2) It guarantee the inter frame quality Consistencies among video frames. HE is a useful technique for improving image contrast, but its effect is too...

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 ...

The most common cancer of women is breast cancer which is the leading cause of cancer-related death among women aged 15 to 54. The risk of cancer increases after the age of 40’s. Thus earlier detection of breast cancer increases the probability of survival of the patient. For its detection mammography is done, but many of the masses remain either undetected or falsely detected due to poor contr...

This paper presents a novel full reference (FR) image quality assessment algorithm by depicting the subband characteristics in the wavelet domain. The proposed image quality assesment method is based on the energy estimation in wavelet transformed image. Image quality assessment is achieved by applying a multi-level wavelet decomposition on the both original and enhanced image. Next, the wavele...
