This dataset was primarily designed and captured to be used for the testing part of the Helsinki Deblur Challenge 2021 but it can be used for any testing and benchmarking purposes of image deblurring algorithms. The dataset contains photographs ofrandom strings of text (including numbers), natural images and QR codeswith varying levels of blur caused by misfocusing the camera. Each photo has both a blurred and sharp version. The images are split into 4 separate zip files each having 5 steps of different blur. Altogether there are 20 steps. Each one of thezip files contains twofolders,one folder named CAM1_focused (Camera 1) with the sharp images and one named CAM2_blurred (Camera 2) with theblurred images. For each step there are 40images oftext character targets, 15 natural image targets,one QR-code target and 3 images of technical targets. Each one of the text target images is accompanied by a text file (same file name but.txt extension) containing the correct transcription of that particular text target. As a difference to the HDC training data (https://doi.org/10.5281/zenodo.4916176) the test data character targets include also numbers.
