  TEC-FP is a convolutional encoder–decoder neural compression model with a fully factorized entropy model for the latent representation. Each quantized latent variable is modeled independently without spatial or channel context.
44
  This design enables efficient parallel entropy coding. TEC-FP is the smallest and fastest image codec in the TerraCodec family and is optimized for 12-band Sentinel-2 imagery.
