Web1 day ago · The image encoder is a particularly large component in the model. This is in contrast to the lightweight mask decoder, which predicts segmentation masks based on the embeddings. Meta AI has made the weights and biases of the model trained on the Segment Anything 1 Billion Mask (SA-1B) dataset available as a model checkpoint. WebGenerating Masks with Comparisons and Bitwise Operations We can extend the pipeline by using some more complex logical conditions. We will use comparison operators to build masks that represent regions where the image has low and high pixel intensities. We will use bitwise OR operation to build a mask that represents the union of this regions.
