Image Type Classifier For Improved Remote Presentation Session Compression

摘要

An invention is disclosed for classifying a graphic—e.g. as text or non-text. In embodiments, machine learning is used to generate a solution for classifying graphics of a graphic based on providing the machine learning system a plurality of graphics that are already classified. The way to determine a classification is then used by a remote presentation session server to classify tiles of frames to be transmitted to a client in a remote presentation session. The server encodes the tiles based on their classifications and transmits the encoded tiles to the client.

主权项

1. A method for classifying tiles to be sent to a computer in a remote presentation session, a tile comprising a plurality of pixels, comprising:
retrieving from storage a stored machine learning classifier, the stored machine learning classifier having been trained via a training process on a training set of pre-classified tiles,
each pre-classified tile of the training set of pre-classified tiles having a feature comprising a numerical value that represents a characteristic of a plurality of pixels of a first pre-classified tile of the training set of pre-classified tiles,the training process comprising using machine learning to determine a function for classifying a set of unclassified tiles based on a correspondence between the feature and a pre-determined classification of the first pre-classified,the training process comprising verifying that providing a feature of a second pre-classified tile of the training set of pre-classified tiles to the stored machine learning classifier causes the stored machine learning classifier to output a pre-determined classification of the second pre-classified tile; using the stored machine learning classifier on a first unclassified graphics tile of a set of unclassified graphics tile to determine classification of the first unclassified graphics tile, and to produce a first classified graphics tile; encoding the first classified graphics tile using a codec selected according to the determination of the machine learning classifier; and sending the encoded first classified graphics tile to the remote device.
