In this correspondence, we propose a novel method to extract illumination insensitive
features for face recognition under varying lighting called the Gradientfaces. Theoretical …

This paper proposes new color local texture features, ie, color local Gabor wavelets
(CLGWs) and color local binary pattern (CLBP), for the purpose of face recognition (FR). The …

This paper proposes a novel face descriptor based on color information, ie, so-called local
color vector binary patterns (LCVBPs), for face recognition (FR). The proposed LCVBP …

This paper presents the concept of color space normalization (CSN) and two CSN
techniques, ie, the within-color-component normalization technique (CSN-I) and the across …

Printed circuit board (PCB) assurance in the optical domain is a crucial field of study.
Though there are many existing PCB assurance methods using image processing, computer …

In recent years, many large-scale information systems in the Internet of Things (IoT) can be
converted into interdependent sensor networks, such as smart cities, smart medical systems …

This paper introduces a tensor perceptual color framework (TPCF) for facial expression
recognition (FER), which is based on information contained in color facial images. The TPCF …

This paper presents an accurate and efficient eye detection method using the discriminatory
Haar features (DHFs) and a new efficient support vector machine (eSVM). The DHFs are …

This research paper introduces two novel color descriptors for Face Recognition (FR) called
as Color ZigZag Binary Pattern (CZZBP) and Color Median Block ZigZag Binary Pattern …

Under a nonideal situation, the image quality may vary. As a result, the traditional iris
recognition systems would not work well. However, these kinds of iris recognition systems …
