    One of the basic tenets of conventional applied colorimetry is that the whole population of color normal observers can be represented by a single “standard” observer with reasonable accuracy. The 1964 CIE standard colorimetric observer has indeed served us well in all industrial color imaging applications, until recently. With the proliferation of modern wide-gamut displays with narr...

    Development and implementation of spatial color algorithms has been an active field of research in image processing for the last few decades. A number of investigations have been carried out so far in mimicking the properties of the human visual system (HVS). Various algorithms and models have been developed, but they produce more or less neutral output. Some applications demand the preservation o... View full abstract»

  • Salient region detection with opponent color boosting

    Publication Year: 2010 , Page(s): 13 - 18

    Numerous efforts have been made to detect salient regions in images. Mostly luminance-based saliency models are found in the literature, which ignore the important contribution of color in finding the local distinct image features. Methods about color saliency detection in the literature can only give indication of color salient points or derivatives. In this paper, we present a fast method for de... View full abstract»

    An automatic algorithm of degraded color document image enhancement is proposed based on our previous work on Natural Rendering of Color Image using Retinex (NRCIR) with respects to document image characteristics. In the proposed work, an adaptive workflow is designed to enhance both luminance and chrominance contrast of document image while maintaining degradations within tolerance and hue-shift ...

  • Analysis and comparison of quality metrics with reference based on uniform colour spaces

    Image quality assessment is becoming increasingly used in many applications. In most of the existing image quality assessment approaches, the main objective is to develop measures that are consistent with the subjective evaluation. Therefore, the performance of a given image quality metric is evaluated against the MOS determined from a series of subjective tests performed on a database. A plethora... View full abstract»

  • Gaze shifts as dynamical random sampling

    Publication Year: 2010 , Page(s): 29 - 34

    We discuss how gaze behavior of an observer can be simulated as a Monte Carlo sampling of a distribution obtained from the saliency map of the observed image. To such end we propose the Levy Hybrid Monte Carlo algorithm, a dynamic Monte Carlo method in which the walk on the distribution landscape is modelled through Levy flights. Some preliminary results are presented comparing with data gathered ... View full abstract»

    In daily interactions, humans convey their emotions through facial expression and other means. There are several facial expressions that reflect distinctive psychological activities such as happiness, surprise or anger. Accurate recognition of these activities via facial image analysis will play a vital role in natural human-computer interfaces, robotics and mimetic games. This paper focuses on th...

  • Adaptive fuzzy commitment scheme based on iris-code error analysis

    Biometric cryptosystems is a group of emerging technologies that securely bind a digital key to a biometric so that no biometric image or template is stored. Focusing on iris biometrics several approaches have been proposed to bind keys to binary iris-codes where the majority of these approaches are based on the so-called fuzzy commitment scheme. In this work we present a new approach to construct... View full abstract»

    Compressed image quality assessment is of increasing importance in image coding systems where the schemes optimization is based on the distortion measure. There exist many distortion measures in the literature which are often validated by comparing them to the human appreciation of the image quality, in particular the Mean Opinion Score (MOS). Until now, we do not know precisely which factors inte... View full abstract»

  • Statistical evaluation of no-reference image visual quality metrics

    A task of no-reference visual quality metric verification is considered. A test set that contains 500 JPEG format images having different distortions is created. The results of experiments carried out by 316 volunteer observers to evaluate visual quality of images are presented. The experiments allowed obtaining mean opinion scores (MOS) based on averaging the evaluations. Several non-reference im... View full abstract»

    In this paper we study image distortions and impairments that affect the perceived quality of blackboard lectures images. We also propose a novel reference free image quality evaluation metric that correlates well with the perceived image quality. The perceived quality of images of blackboard lecture contents is mostly affected by the presence of noise, blur and compression artifacts. Therefore, t... View full abstract»

  • Segmentation-based document image denoising

    In this work, a robust method of document images denoising is presented. The simple idea is combining the NLM filter and a Markovian segmentation into regions. The NLM method filtering allows participation of far, but proper pixels in the denoising process. Although the weights of non-similar (irrelevant) pixels are very small, high number of these pixels results in introduction of blur. In this w... View full abstract»

    Indexing of news video streams with semantic keywords is of interest to agencies that regularly monitor many news channels. In this paper, we describe a new method for indexing news video in different languages, for which there are inadequate language tools. Our approach involves combining multimodal inputs, namely audio and visual, and spotting of a handful of keywords with higher reliability, as... View full abstract»

    Reversible data hiding deals with the insertion of auxiliary information into a host data without causing any permanent degradation to the original signal. In this paper a novel reversible data hiding scheme, based on the classical Difference Expansion insertion algorithm, is presented. A prediction stage is adopted in the transform domain and the embedding algorithm is applied to computed predict... View full abstract»

    In this paper, we describe a smart surveillance system to detect human faces in stereo images with applications to advanced video surveillance systems. The system utilizes two smart IP cameras to obtain the position and location of the object that is a human face. The position and location of the object are extracted from two IP cameras and subsequently transmitted to a Pan-Tilt-Zoom (PTZ) camera,... View full abstract»
