![]() > file-sizes range across with an average of 4 MB. Learn how to select inputs, outputs and tasks with 'anchor -h'. InputsĬonsider an example album with three images. This tutorial proceeds to show how Anchor can create histograms for each channel in an image, and derive a summed histogram aggregated across many images. Here, histograms help explore and calculate appropriate normalization, including sanity checks on content. subtracting a mean intensity value from image channels. With deep learning workflows, data normalization is also a popular step e.g. With classical image processing, popular thresholding algorithms like Otsu’s method use the image histogram (or histograms derived from image subregions) to determine appropriate thresholds. The histograms can be used in subsequent processing steps for normalizing operations, either against the image’s histogram itself, or against an aggregated histogram from many related images. Generating histograms can be a useful first step for image exploration and understanding. Image histograms describe the color (pixel intensity) content of an image. ![]()
