Subspace learning methods are very sensitive to the illumination, translation, and rotation variances in image recognition. Thus, they have not obtained promising performance for palmprint recognition so far. In this paper, we propose a new descriptor of named histogram oriented lines (HOL), which is variant gradients (HOG). HOL changes has robustness against small transformations because slight translations rotations make value changes. Based on HOL, even some simple subspace can achieve high rates.

In this paper, the problem of Palmprint Recognition Across Different Devices (PRADD) is investigated, which has not been well studied so far. Since there no publicly available PRADD image database, we created a non-contact database containing 12,000 grayscale captured from 100 subjects using three devices, i.e., one digital camera and two smart-phones. Due to acquisition used, rotation scale changes between different images same palm are inevitable. We propose robust method calculate width,...

The pervasion of 3-D technologies over the years gives rise to increasing demands accurate and efficient stereoscopic image quality assessment (SIQA) methods, designed automatically supervise optimize video processing systems. Though 2-D IQA has attracted considerable attention, its counterpart is yet be well explored. In this paper, a no-reference SIQA method using convolution neural network (CNN) for feature extraction proposed. proposed method, CNN model trained from scratch classify...

With the booming of 3-D image processing in entertainment industry and multimedia applications todays, technology for assessing quality stereoscopic faces more challenging tasks than its 2-D counterparts, such as binocular combination, stereo matching, rivalry. In this paper, a novel assessment method is proposed by jointly exploring fusion rivalry models. quality-aware feature extraction stage, multi-scale combination energy responses are first generated from reference distorted...

In this paper, a new Local Binary Pattern (LBP) and Ternary based palmprint identification method is proposed. our method, LBP or LTP descriptor applied to the energy direction representations of extracted by modified finite radon transformation (MFRAT). Experimental results obtained from Hong Kong Polytechnic University (PolyU) Palmprint Database demonstrate that proposed has higher rates than other methods.

Bladder cancer is reported to be the fifth leading cause of deaths in United States. Recent advances medical imaging technologies, such as magnetic resonance (MR) imaging, make virtual cystoscopy a potential alternative clinical optical with advantages being safe and non-invasive method for evaluation entire bladder detection abnormalities. To help reduce interpretation time reading fatigue readers or radiologists using MR cystoscopy, computer-aided scheme widely employed, where thickness...

Partial discharge detection is an effective method for evaluating the insulation condition of cable accessories. Ultra-high-frequency detecting partial has strong anti-interference ability. Therefore, a broadband, circularly polarized Archimedean planar spiral antenna used as sensor. After determining parameters through theoretical calculations, simulate and design antenna. Analyze influence different inner diameter values on performance. Exponential gradient microstrip balun added to...

Based on BAYES data processing theory, a new method of fuzzy probability is proposed for the parameter reliability small sample. Prior distribution obtained by stochastic weighted method, then posterior got conjugate distribution. In end, formula membership function constructed, and events solved.The study this paper aims at which deduced in condition that mean known deviation unknown normal population At same time using information sample actual experiment, fully utilizes prior information,...

Image quality assessment (IQA) is desired to evaluate the perceptual of an image in a manner consistent with subjective rating. Considering characteristics hierarchical visual cortex, novel full reference IQA method proposed this paper. Quality-aware features that human system sensitive are extracted describe comprehensively. Concretely, log Gabor filters and local tetra patterns employed capture spatial frequency texture features, which attractive primary secondary respectively. Moreover,...
