High precision frequency quantization for image and video encoding
AbstractTechniques for high precision frequency quantization for image and video (e.g., frame) encoding are described. According to some embodiments, a computer-implemented method includes receiving a request to encode a video from a first depth of pixel values to a second, lower depth of pixel values at a content delivery service, performing a frequency transformation on a full fidelity of the first depth of pixel values of a frame of the video to generate frequency coefficient values, performing a quantization on the frequency coefficient values to generate quantized frequency coefficient values, encoding the quantized frequency coefficient values of the frame into an encoded frame having the second, lower depth of pixel values by the content delivery service, and transmitting the encoded frame from the content delivery service to a viewer device.
