WebNov 28, 2024 · A downsampling method is described to predict the YI and AUC achievable with a large number of patients.
WebGIMP has a "Sinc (Lanczos 3)" interpolation method, which is excellent for downsampling. However if the original images are large, with lots of small details such as film grain, and you are downsampling much smaller, then there's not really much you can do. Details will be lost when resampling, no matter what you do.
