This is the place for information and Matlab code for the edge-based camera resolution evaluation. Version 4 of the ISO standard 12233 was published on 27 Feb. 2023, and the Matlab code is posted here.
Please note: The edge feature in the test image must pass through two corresponding edges of the region of interest (ROI) used for the analysis. The edge must pass through either the top and bottom or the left and right margins of the ROI.
