SharpnessReclassificationDataset contains three data folders, each representing a different scene or subject, with images defocused using a constant defocus step.
Chart and Tools Folder: Contains images defocused on one side (focus toward the camera).
Smear Folder: Contains 10 images from each side of the optimal focus. Image 0 is the best focus. Negative numbers from 0 are increasingly defocused images from one side, while increasingly positive numbers from 0 are defocused images from the other side.
Those images are used to demonstrate the effectiveness of a new sharpness evaluation tool within the logarithmic image processing framework (LIP), enabling the reclassification of images based on sharpness and paving the way for new autofocus tools.
