Appropriate image preprocessing could improve machine learning performance, but the robustness of to methods in micrograph datasets with significant sample differences remains unexplored. Here we collected hundreds optical micrographs varied color, contrast, size and brightness tensile strength from published literature. After including color transformation, adjustment, normalization enhancement, classification model whether it was texture or not prediction were established using transfer...
