“Decoding Bird Species Diversity through Image Analysis

Abstract

Bird species diversity plays an integral role in maintaining ecosystem equilibrium and serves as a significant indicator of environmental health. However, the meticulous monitoring and cataloging of bird species within specific regions pose considerable challenges, often requiring extensive time and expertise from ornithologists. In today's rapidly advancing technological landscape, the integration of image analysis and machine learning presents a promising avenue to streamline bird species identification and diversity assessment processes. Nonetheless, the increasing rarity of certain bird species presents a formidable obstacle, complicating their classification. Birds encountered across diverse environments present varying sizes, shapes, colors, and orientations, adding complexity to accurate identification via image analysis. Moreover, image- based classification exhibits more pronounced variations compared to audio classification, although human perception of birds through images remains intuitively comprehensible. Leveraging the deep convolutional neural network (DCNN) algorithm, images undergo conversion into grayscale format to generate autographs using TensorFlow, resulting in the creation of multiple comparison nodes. Subsequently, these nodes undergo comparison with the testing dataset, generating a score sheet for analysis. Interpretation of this score sheet facilitates the prediction of the target bird species based on the highest score achieved. Experimental analysis conducted on datasets such as Caltech-UCSD Birds demonstrates the algorithm's efficacy, with bird identification accuracy ranging between 80% and 90%.
