Title: Innovations of Alexandra R Ohlson
Introduction
Alexandra R Ohlson is a notable inventor based in Palo Alto, CA (US). She has made significant contributions to the field of image processing, holding 2 patents that showcase her innovative approach to optimizing image operations.
Latest Patents
Her latest patents include a method, apparatus, and computer program product for using deferred execution for a tiling pull model in a tiled image processing architecture. This invention optimizes the application of deferred image operations on a tiled source image by dynamically creating a data structure, such as a directed acyclic graph (DAG), to represent the operations performed on various instances of one or more images. The invention analyzes this data structure to determine which source image tiles are needed when the final image data is required. This approach reduces the number of times a tile is read into memory for processing, thereby improving the performance of deferred image operations.
Another significant patent by Ohlson is a method, apparatus, and computer program product for eliminating edge. This invention reduces the overhead associated with performing area-image operations on a tiled image by detecting when an area-image operation requires pixel values from adjacent tiles. It generates a list of boxes representing pixel image information, which are split with respect to the image edges and tile edges. This mechanism allows for the assembly of image data that crosses tile edges without the need to copy major portions of the tile from one memory buffer to another.
