Impact of image quality and artifacts on insect wing asymmetry analysis. (a) Case 1: Normal images of the left and right wings of a damselfly at 300 DPI. (b) Case 2: Noise added to the left wing image of the damselfly. (c) Case 3: The left wing image blurred using Gaussian Blur with a radius of one pixel in Photoshop. Case 4 (not illustrated): Similar to Case 1, but with increased resolution to 400 DPI. (d) Comparison of wing area differences. (e) Comparison of wing cell area, length, width, and circularity regressions. (f) Comparison of wing centroids, junctions, and outline mean distance across the four cases.
