This contribution focuses on different topics covered by the special issue titled ‘Hardware Implementation of Machine vision Systems’ including FPGAs, GPUS, embedded systems, multicore implementations for image analysis such as edge detection, segmentation, pattern recognition and object recognition/interpretation, image enhancement/restoration, image/video compression, image similarity and ret...

Visual coding is a highly dynamic process and continuously adapting to the current viewing context. The perceptual changes that result from adaptation to recently viewed stimuli remain a powerful and popular tool for analyzing sensory mechanisms and plasticity. Over the last decade, the footprints of this adaptation have been tracked to both higher and lower levels of the visual pathway and ove...

The paper we present pGBbBShift. This algorithm permits to code any Region of Interest (ROI) in a perceptual way, i.e. the presented algorithm introduces some characteristics of the HumanVisual System. Furthermore, it introduces features of chromatic induction to the GBbBShift method when bitplanes of ROI and background areas are coded. Thus, the included features balance visual importance of s...

How visual information is encoded in spikes of retinal ganglion cells (RGCs) is essential in visual neuroscience. In the present study, we investigated the coding properties of mouse RGCs with dual-peak patterns with respect to visual stimulus intervals. We first analyzed the response properties, and observed that the latencies and spike counts of the two response peaks in the dual-peak pattern...

in video coding, intra coding plays an important role in both coding efficiency and error resilience, and current intra coding methods still have great potential to be further investigated. In this paper, a high performance intra coding method based on video epitomic analysis is proposed. Epitomic priors suitable for coding are extracted through video epitomic analysis, and are used to generate...

In this paper, a segmentation -based image coding technique incorporating properties of the human visual system is presented. The approach taken in this research is to first segment an image into regions with spatial similarity and then to define an efficient method for encoding the segmented image data. Furthermore, specific attention is given in this paper to defining the requirements for usi...

Objective methods for assessing perceptual image quality traditionally attempt to quantify the visibility of errors (differences) between a distorted image and a reference image using a variety of known properties of the human visual system. Under the assumption that human visual perception is highly adapted for extracting structural information from a scene, we introduce an alternative complem...

This paper reports an adaptive still color image compression method which produces automatically-selected ROIs with a higher reconstruction quality with respect to the rest of the input image. The ROIs are generated on-thefly with a purely data-driven technique based on visual attention. Inspired from biological vision, the multicue visual attention algorithm detects the most visually-salient r...
