In this paper, we described and developed a framework for Multilayer Perceptron (MLP) to work on low level image processing, where MLP will be used to perform image super-resolution. Meanwhile, MLP are trained with different types of images from various categories, hence analyse the behaviour and performance of the neural network. The tests are carried out using qualitative test, in which Mean ...

Image Quality assessment plays an important role in various image processing applications. It is still an active field of research. A great deal of effort has been made in recent years to develop objective image quality metrics that correlate well with perceived human quality measurement or subjective methods. Most full reference(FR) technique were derived based on pixel to pixel error such as ...

The major purpose of this paper is to transmit an existing video above a complete simulated video streaming architecture based on Network Simulator (NS2). Thanks to our architecture, the visual quality evaluation of the distributed streaming platform under various conditions is simplified. Indeed, the received video can be easily visualized using a classic video client or be compared using the ...

In this paper the authors present a methodology for building a model for packet loss effect on High Definition video content. The goal is achieved using the SSIM video quality metric, temporal pooling techniques and content characteristics. Subjective tests were performed in order to verify proposed models. An influence of several network loss patterns on diverse video content is analyzed. The ...

Localization and segmentation of Optic Disk (OD) is an important prerequisite for automatic detection of Diabetic Retinopathy (DR) from digital retinal fundus images. Considerable research has been done to isolate OD with varying degrees of success but on a limited number of images. In this paper we propose a novel algorithm based on Independent Component Analysis (ICA) coupled with a modified ...

This paper presents a JPEG-like coder for image compression of single-sensor camera images using a Bayer Color Filter Array (CFA). The originality of the method is a joint scheme of compression.demosaicking in the DCT domain. In this method, the captured CFA raw data is first separated in four distinct components and then converted to YCbCr. A JPEG compression scheme is then applied. At the dec...

Use of Ultra-wideband (UWB) for wireless communication in home networking requires cost effective technical solutions with high quality. This paper investigates the performance of simple receiver with zero forcing equalizer in place of rake receiver for hermite based UWB communication. The UWB system with simple receiver is simulated for the application of image transmission over IEEE UWB chann...

We examine the effect that variations in the temporal quality of videos have on global video quality. We also propose a general framework for constructing temporal video quality assessment (QA) algorithms that seek to assess transient temporal errors, such as packet losses. The proposed framework modifies simple frame-based quality assessment algorithms by incorporating a temporal quality varia...

Shearlet as a new multidirectional and multiscale transform is optimally efficient in representing images containing edges. In this paper, a total variation based multivariate shearlet adaptive shrinkage is proposed for discontinuity-preserving image denoising. The multivariate adaptive threshold is employed to reduce the noise. Projected total variation diffusion is used to suppress the pseudo...

Assessing the Quality of Experience (QoE) for multimedia services transmitted over a network has become a major issue for telecom providers (Telcos), because it can determine the real user satisfaction regarding the service they hire. For this reason, we present the metrics based on the Reduced Reference (RR) methodology called Quality Index Based Frame (IQBF) and New Undecodable Frames Index (...
