Abstract
Due to the rapidly increasing quality of cameras and processing power in smartphones, citizen scientists can play a more significant role in environmental monitoring and ecological observations. Determining the size of large bird flocks, like those observed during migration seasons, is important for monitoring the abundance of bird populations as wildlife habitats continue to shrink. This paper describes a pilot study aimed at automatically counting birds in large moving flocks, filmed using hand-held devices. Our proposed approach integrates motion analysis and segmentation methods to cluster and count birds from video data. Our main contribution is the design of a bird counting algorithm that requires no human input, and functions well for videos acquired in non-ideal conditions. Experimental evaluation is performed using ground truth of manual annotations and bird counts, and shows promising results.
