Abstract
A system classifies a compressed image or predicts likelihood values associated with a compressed image. The system partially decompresses compressed JPEG image data to obtain blocks of discrete cosine transform (DCT) coefficients that represent the image. The system may apply various transform functions to the individual blocks of DCT coefficients to resize the blocks so that they may be input together into a neural network for analysis. Weights of the neural network may be trained to accept transformed blocks of DCT coefficients which may be less computationally intensive than accepting raw image data as input.
