Face detection is a crucial step in many vision applica-tions. Since the Viola and Jones face detector, many feature extraction approches based Adaboost are proposed.This paper presents a novel approach to extract effective features for face detection system. Both LBP and three Patch LBP (TPLBP) with joint integral histogram are used to extract features. The joint integral histogram was firstly...

Feature Extraction Features are extracted using a two-layer stacked auto-encoder (SAE) with 1440 input neurons, 500 first hidden layer neurons and 100 2nd layer hidden neurons. Each CQT input patch consists 8 frames with 180 frequency bins or one measure of the song and each chroma feature input consists of 144 frequency bins and 10 frames with 50% overlap. The SAE is then trained on a set of c...

Unsupervised pixel-level defective region segmentation is an important task in image-based anomaly detection for various industrial applications. The state-of-the-art methods have their own advantages and limitations: matrix-decomposition-based are robust to noise, but lack complex background image modeling capability; representation-based good at localization, accuracy shape contour extraction...

Abstract Interstitial fluid (ISF) is a body that fills, surrounds cells and contains various biomarkers, but it has been challenging to extract ISF in reliable sufficient amount with high speed. To address the issues, we developed tilted microneedle collecting system (TMICS) fabricated by 3D printing. In this system, (MN) was inserted at 66° skin TMICS so MN length could be extended within safe...

Script identification plays a significant role in analysing documents and videos. In this paper, we focus on the problem of script identification in scene text images and video scripts. Because of low image quality, complex background and similar layout of characters shared by some scripts like Greek, Latin, etc., text recognition in those cases become challenging. Most of the recent approaches...

Chest radiography (CXR) has been used as an effective tool for screening tuberculosis (TB). Because of the lack of radiological expertise in resource-constrained regions, automatic analysis of CXR is appealing as a “first reader”. In addition to screening the CXR for disease, it is critical to highlight locations of the disease in abnormal CXRs. In this paper, we focus on the task of locating T...

Open geospatial data sources provide opportunities for low cost 3D scene reconstruction. In this study, based on a sparse airborne laser scanning (ALS) point cloud (0.8 points/m2) obtained from open source databases, a building reconstruction pipeline for CAD building models was developed. The pipeline includes voxel-based roof patch segmentation, extraction of the key-points representing the r...

Experimental investigation of the ultimate resistance of slender, steel-plate girder web panels to combined shear-and-patch loading indicates significant interaction between shear loading and patch loading. However, an existing interaction formula is based on experimental results. Herein, an improved design procedure for slender plate girders subjected to combined shear and patch loading is pro...
