An Angler‐Friendly AI Pipeline for Self‐Reporting and Automatic Catch Analysis in Recreational Fisheries

Fish and Fisheries, Volume 27, Issue 3, Page 627-642, May 2026.
ABSTRACT Monitoring recreational fisheries is difficult: anglers are widely dispersed, gear and practices vary, and many species are involved, which leads to fragmented and scarce data. To address these issues, we developed an Artificial Intelligence (AI) pipeline that turns angler‐reported photos into standardised records of catch composition and ...

Unsupervised Multi-Scale-Stage Content-Aware Homography Estimation

, 2023
Homography estimation is a critical component in many computer-vision tasks. However, most deep homography methods focus on extracting local features and ignore global features or the corresponding relationship between features from two images or video ...

SemFlow: Semantic-Driven Interpolation for Large Displacement Optical Flow

IEEE Access, 2019
This paper presents a semantic-guided interpolation scheme (SemFlow) to handle motion boundaries and occlusions in large displacement optical flow. The basic idea is to segment images into superpixels and estimate their homographies for interpolation. In

A New GRIME2: Using an Octagon Calibration Target and Trail Camera to Measure Stream Water Level Over a 2‐Year Period

Water Resources Research, Volume 62, Issue 3, March 2026.
Abstract GaugeCam Remote Image Manager Educational 2 (GRIME2) is a free, open‐source Windows application for water level measurement in surface water bodies using ground‐based time‐lapse imagery. We evaluated a new “stop sign” (i.e., octagon shape) calibration target and GRIME2 algorithms by comparing results to other measurement methods over a 26 ...
