Automatic thresholding for defect detection
Pattern Recognition Letters, 2005Automatic thresholding has been widely used in the machine vision industry for automated visual inspection of defects. A commonly used thresholding technique, the Otsu method, provides satisfactory results for thresholding an image with histogram of bimodal distribution. This method, however, fails if the histogram is unimodal or close to unimodal. For

Automatic Detection and Classification of Sewer Defects via Hierarchical Deep Learning
IEEE Transactions on Automation Science and Engineering, 2019Video and image sources are frequently applied in the area of defect inspection in industrial community. For the recognition and classification of sewer defects, a significant number of videos and images of sewers are collected.

Automatic detection of orientation variance
Neuroscience Letters, 2017Rapid extraction of the overall statistics of the visual scene is crucial for the human ability to rapidly perceive the general 'gist'. The aim of this work was to investigate if there exists neural evidence for such a process i.e. automatic, unattended detection of overall statistical differences between scenes.

Automatic image orientation detection
IEEE Transactions on Image Processing, 2002We present an algorithm for automatic image orientation estimation using a Bayesian learning framework. We demonstrate that a small codebook (the optimal size of codebook is selected using a modified MDL criterion) extracted from a learning vector quantizer (LVQ) can be used to estimate the class-conditional densities of the observed features needed ...

Automatic Detection of MPI Assertions
2020The 2019 MPI standard draft specification includes the addition of defined communicator info hints. These hints are assertions that an application makes to an MPI implementation, so that a more optimized implementation is possible. The 2019 draft specifications defines four assertions: mpi_assert_no_any_tag, mpi_assert_no_any_source ...

System for automatic faces detection
2012 3rd International Conference on Image Processing Theory, Tools and Applications (IPTA), 2012The effectiveness of biometric authentication based on face mainly depends on the method used to locate the face in the image or video. This paper presents a hybrid system for faces detection, in a color image or video, in unconstrained cases, i.e. situations in which illumination, pose, occlusion and size of the face are uncontrolled.

Automatic motion detection for surveillance
Artificial Life and Robotics, 2007Automatic motion detection features are able to enhance surveillance efficiency and quality. The aim of this research is to recognize and detect motion automatically around a robot's environment in order to equip a mobile robot for a surveillance task.

Automatic Detection of Survey Articles
2005We propose a method for detecting survey articles in a multilingual database. Generally, a survey article cites many important papers in a research domain. Using this feature, it is possible to detect survey articles. We applied HITS, which was devised to retrieve Web pages using the notions of authority and hub.
