Abstract The traditional Local Binary Pattern (LBP) employs a 3x3 pixel window and
examines the intensity differences between the center pixel and nearby neighbourhood …

The traditional Local binary pattern (LBP) compares the central pixel with all 8-neighboring
pixels in a 3× 3 pixel window to generate LBP codes. However, its circular structure may …

This paper presents a novel approach in feature extraction, Local Symmetric Directional
Pattern (LSDP), for face recognition. The LSDP encodes the structure of facial textures …

Literature suggests that by fusing multiple features there is immense improvement in the
recognition rates as compared to the recognition rates of single descriptor. This motivate …

The influence of light changes makes the task of feature extraction more difficult for the local
descriptors. Most of local descriptors sacrifices their performance in harsh lightning …

This paper proposes a novel descriptor called Mean-Variance-Median based Local binary
pattern (MVM-LBP). The Median binary pattern (MBP) calculates the difference between …

Among several local descriptors invented in literature, the local binary pattern (LBP) is the
prolific one. Despite its advantages like low computational complexity and monotonic gray …

Most of the existing local descriptors unable to perform well in front of noise and blur
variations. Additionally there are very less descriptors persist in literature which are noise …

Human perception of visual stimulus and its physical characteristics have a nonlinear-
logarithmic relation as stated in Fechner's law, which is a psychophysical law of perception …

Image Enhancement is crucial phase of particular application. These enhancement
techniques become essential when there is every possibility of image degradation due to …
