Robust multi-clue face tracking system [PDF]

, 2009
In this paper we present a multi-clue face tracking system, based on the combination of a face detector and two independent trackers. The detector, a variant of the Viola-Jones algorithm, is set to generate very low false positive error rate.

Advanced Paternal Age Impacts Common Loci in the Sperm and Placenta DNA Methylomes

Andrology, Volume 14, Issue 2, Page 528-544, February 2026.
ABSTRACT Background Epidemiological studies have reported an association between advanced paternal age at conception and an increased risk of neurodevelopmental disorders in offspring, such as autism spectrum disorder. Evidence suggests that DNA methylation alterations in spermatozoa of older men may be transmitted to the feto‐placental unit and ...

An improved algorithm on Viola-Jones object detector

2012 10th International Workshop on Content-Based Multimedia Indexing (CBMI), 2012
In image processing, Viola-Jones object detector [1] is one of the most successful and widely used object detectors. A popular implementation used by the community is the one in OpenCV. The detector shows its strong power in detecting faces, but we found it hard to be extended to other kinds of objects.

Bengali License Plate Detection using Viola-Jones Algorithm

International Journal of Innovative Technology and Exploring Engineering, 2019
Image classification has been a rapidly developing field over the previous decade, and the utilization of Convolutional Neural Networks (CNNs) and other deep learning techniques is developing rapidly. However, CNNs are compute-intensive. Another algorithm which was broadly utilized and keeps on being utilized is the Viola-Jones algorithm.
