Latest Patents

Watras holds a patent for a "System and method for defect detection using a conditional masked autoencoder." This method involves receiving an optical image of a sample and dividing it into multiple image patches. The process includes generating a masked optical image by selectively masking these patches based on characterization data. The masked optical image is then provided to a first encoder, while a design image is sent to a second encoder. The invention generates feature vectors from both encoders, which are concatenated to create a reference image of the sample. This reference image serves as a reconstructed version of the optical image and the design image, showcasing the effectiveness of his approach in defect detection.
