Batch input for image preprocessing and KNN classification
显示 更早的评论
Hi everyone, how can I batch input the jpg file for image preprocessing? For my data 029 actually is an image which split into small image and some of the image like 029-119, 029-120 have no crack on it.
Q1: How can i batch input it?
Q2 How can I define it as crack if either one part of the 029 image is crack? Much appreciate.

You could do one of these three things (incomplete list):
- Use an imageDatastore object for your image collection and the ReadFcn for preprocessing (might be slow)
- Use the preprocessing capabilities of the Deep Learning Toolbox
- Write a function that preprocesses a single image given the images file name as function input. Call the function with arrayfun / cellfun and an array / cell array of filenames
