A Novel Combined System of Direction Estimation and Sound Zooming of Multiple Speakers [PDF]

open access: yes, 2015
This article presents a new system for estimation the direction of multiple speakers and zooming the sound of one of them at a time. The proposed system is a combination of two levels; namely, sound source direction estimation, and acoustic zooming.

Circulant temporal encoding for video retrieval and temporal alignment [PDF]

open access: yes, 2015
We address the problem of specific video event retrieval. Given a query video of a specific event, e.g., a concert of Madonna, the goal is to retrieve other videos of the same event that temporally overlap with the query.

A Novel Dual‐Network Approach for Real‐Time Liveweight Estimation in Precision Livestock Management

open access: yesAdvanced Science, Volume 12, Issue 22, June 12, 2025.
A novel dual‐network framework is proposed for real‐time, non‐contact liveweight estimation of pigs. By extracting contour information instead of segmented images, the method achieves high accuracy (R2 = 0.993) and an exceptional speed of 1131.6 FPS. This approach enhances automation in livestock farming, providing a scalable and efficient solution for

Impact Analysis of Baseband Quantizer on Coding Efficiency for HDR Video

open access: yes, 2016
Digitally acquired high dynamic range (HDR) video baseband signal can take 10 to 12 bits per color channel. It is economically important to be able to reuse the legacy 8 or 10-bit video codecs to efficiently compress the HDR video.
