This paper describes a method for the development of Bangla Enconversion within the framework of the Universal Networking Language (UNL).We also discuss some issues and problems related to the UNL representation that affect the quality of generation. Additionally, the lingware engineering is introduced as a technique to enhance the quality and increase the development efficiency. In this paper,...

This paper presents a novel technique for color image compression in the transform domain. For compression of images vector quantization (VQ) technique is used and the codebook in VQ is designed using Kohonen’s Self Organizing Feature Maps (SOFM). This work exploits the special features of SOFM for generic codebook generation that enables to construct the codebook only once. Apart from spatial ...

In this article, we compare direct image transmissions through various multimode optical fibers, namely, step-index silica, graded-index silica, and step-index plastic fibers. We make use of a round-trip transmission in the optical fiber as well as a phase-conjugate wave generated by a self-pumped BaTiO3 crystal to recover a distorted image. The image was best recovered for a step-index silica ...

In order to handle complex face image variations in face recognition, multi-image face recognition has been proposed, instead of using a single still-imagebased approach. In many practical scenarios, multiple images can be easily obtained in enrollment and query stages, for example, using video. By accessing these images, a good ”quality” image(s) will be used for recognition using conventional...

State-of-the-art pansharpening methods generally inject the spatial structures of a high spatial resolution (HR) panchromatic (PAN) image into the corresponding low spatial resolution (LR) multispectral (MS) image by an injection model. In this paper, a novel pansharpening method with an edge-preserving guided filter based on three-layer decomposition is proposed. In the proposed method, the PA...

Image quality metrics have been widely used in imaging systems to maintain and improve the quality of images being processed and transmitted. Due to the close relationship between image quality perception and the human visual system, the development of image quality metrics has been contributed to by both psychologists and computer scientists. In this paper, three novel image quality metrics ar...

The features of the metrics for assessing quality work classifier recognizing small-sized objects on radar image are considered, they compared and most universal informative ones identified.

Image quality is a characteristic of an image that measures the perceived image degradation (typically, compared to an ideal or perfect image). Imaging systems may introduce some amounts of distortion or artifacts in the signal, so the quality assessment is an important problem JPEG compression is the most prevalent technique or method for image codec’s. But it suffers from blocking artifacts. ...
