  • Patent number: 12141945
    Abstract: Techniques are disclosed for training and applying a denoising model. The denoising model includes multiple specialized denoisers and a generalizer, each of which is a machine learning model. The specialized denoisers are trained to denoise images associated with specific ranges of noise parameters. The generalizer is trained to generate per-pixel denoising kernels for denoising images associated with arbitrary noise parameters using outputs of the specialized denoisers. Subsequent to training, a noisy image, such as a live-action image or a rendered image, can be denoised by inputting the noisy image into the specialized denoisers to obtain intermediate denoised images that are then input, along with the noisy image, into the generalizer to obtain per-pixel denoising kernels, which can be normalized and applied to denoise the noisy image.

  • Publication number: 20240303652
    Abstract: The present invention relates to a digital transaction between a sender (S) and a recipient (R), wherein the digital transaction is certified by a central bank (B), while preserving the privacy of the transaction (T). In particular the transaction (T) is based on a first sender serial number (SSNi) and a first receiver serial number, both signed by the central bank (B) and dedicated to the transaction. The transaction is in addition based on commitment to a value, which is encrypted with a blind factor (BTx) and involves sender zero-knowledge proof (zKs) and receiver zero-knowledge proof (zKr) so that the central bank (B) has no knowledge of the value of the transaction neither of the identity of the sender and the receiver. The present invention also relates to a system and to a digital currency allowing such a digital transaction.

  • Publication number: 20240305801
    Abstract: In some embodiments, a system includes a first component to extract temporal features from a current frame being coded and a previous frame of a video. A second component uses a first transformer to fuse spatial features from the current frame with the temporal features to generate spatio-temporal features as first output. A third component uses a second transformer to perform entropy coding using the first output and at least a portion of the temporal features to generate a second output. A fourth component uses a third transformer to reconstruct the current frame based on the first output that is processed using the second output and the temporal features.

  • Patent number: 12087024
    Abstract: According to one implementation, an image compression system includes a computing platform having a hardware processor and a system memory storing a software code. The hardware processor executes the software code to receive an input image, transform the input image to a latent space representation of the input image, and quantize the latent space representation of the input image to produce multiple quantized latents. The hardware processor further executes the software code to encode the quantized latents using a probability density function of the latent space representation of the input image, to generate a bitstream, and convert the bitstream into an output image corresponding to the input image. The probability density function of the latent space representation of the input image is obtained based on a normalizing flow mapping of one of the input image or the latent space representation of the input image.

  • Publication number: 20240295564
    Abstract: In a method for analyzing cells, a sample fluid having a suspending medium and cells is fed to a microfluidic device having at least one cell processing unit having a trapping region, a reaction unit, and an outlet arrangement. The trapping region is delimited by at least an input valve and a sieve valve, in particular a v-type valve that is capable of retaining the cells while letting fluids pass. The method includes trapping cells in the trapping region, subsequently establishing a flow of a reaction fluid through the trapping region while the sieve valve assumes the open state, such that the reaction fluid transfers the trapped cells from the trapping region into the reaction unit, decomposing the transferred cells into cell fragments through a decomposition process, collecting the cell fragments in the outlet arrangement, and analyzing the cell fragments.
