Publication number: 20230305489Abstract: According to examples, a learning based, end-to-end compression system may include an encoder, which may receive a complex hologram image and encode a latent code for a real component and an imaginary component of the hologram image. The system may also include a quantizer to quantize the latent code and a transform block, which may entropy-code the quantized latent code to obtain a compressed image. The system may further include a generator to decode the compressed image and a discriminator, which may classify the decoded image to obtain an uncompressed image. In case of holographic video input, the encoder may encode a frame to obtain a standard compressed frame and a residual to a latent code. The generator may decode the standard compressed frame and the latent code to obtain a reconstructed residual, and the discriminator may combine the uncompressed standard frame and the reconstructed residual.Type: ApplicationFiled: March 23, 2022Publication date: September 28, 2023Applicant: Meta Platforms Technologies, LLCInventors: Changwon JANG, Richard WEBB, Liang SHI, Lei XIAO, Changil KIM, Douglas Robert LANMAN

Patent number: 11748914Abstract: In one embodiment, a computing system may access color components of a pixel region in an image, and then determine a color variance for each of the color components. The computing system may further determine a desired bit allocation for each of the color components based on the color variance associated with that color component. The computing system may then determine a total bit allocation for the pixel region based on the desired bit allocations for the color components, as well as a number of unallocated bits available for allocation. The computing system may further determine a final bit allocation for each of the color components by allocating the total bit allocation to each of the color components according to the desired bit allocation for each of the color components. The computing system may then encode each of the color components using the associated final bit allocation.Type: GrantFiled: August 26, 2020Date of Patent: September 5, 2023Assignee: Meta Platforms Technologies, LLCInventors: Cheng Chang, Zhi Zhou, Richard Webb, Richard Lawrence Greene

Publication number: 20230215054Abstract: A computing system may access first alpha values associated with first pixels in a first pixel region of an image and determine a bit budget for encoding the first alpha values. The computing system may then select a first alpha-encoding mode for the first alpha values to reflect a determination that the first alpha values are all fully transparent or all fully opaque, and encode the first alpha values by storing the selected first alpha-encoding mode as part of a metadata without using the bit budget to encode the first alpha values individually. The computing system may then update a record of unallocated bits available for allocation based on the bit budget unused in the encoding of the first alpha values, and allocate, based on the record of unallocated bits, bits to encode a set of alpha values different from the first alpha values.Type: ApplicationFiled: March 10, 2023Publication date: July 6, 2023Inventors: Cheng Chang, Zhi Zhou, Richard Webb, Richard Lawrence Greene
