Approaches presented herein provide for the high quality, high resolution reconstruction of a sequence of decimated images, such as may be useful for remote desktop applications. The video frames can be sub-sampled or decimated such that each encoded frame only includes a fraction (e.g., ¼) of the total pixel values for the full resolution frame. A server can analyze the current and previous video frames at full resolution to determine motion or actionable changes, and can apply a lowpass filter to those values based on the type of interpolation to be performed on the client. Static values can remain where no motion is detected. When a client receives the decimated and encoded video frames, the client can determine areas of motion and can perform bilinear interpolation for only those portions of the image where motion is detected, and can otherwise perform weaving of the static pixel values received over a limited sequence of decimated video frames.

A terminal access control system uses HTML5-based graphic acceleration for the secure retrieval and transmission of image data. The system detects a Remote Desktop Protocol (RDP) access attempt and identifies an acceleration target by checking if the category of retrieved information corresponds to an HTML5-transmittable image. A Graphic Acceleration Processing Unit (GPU-equipped) performs the HTML5-based acceleration process, analyzes image frames, and generates processed image information for secure transmission. A Viewing Access Control Unit then verifies the processed data against security policies received from a linked policy server. If the security policy is satisfied and the user is logged in, an Image Restoration and Output Unit performs a decryption and restoration process on the received information, outputting the final image content based on the original request.

The approaches presented here provide high-quality, high-resolution reconstruction of a sequence of decimated images, which can be useful, for example, for remote desktop applications. The video frames can be subsampled or decimated so that each encoded frame includes only a fraction (e.g., 1 / 4) of the total image values ​​for the full-resolution frame. A server can analyze the current and preceding full-resolution video frames to determine motion or actionable changes and can apply a low-pass filter to these values ​​based on the type of interpolation to be performed on the client. Static values ​​can remain where no motion is detected.When a client receives the decimated and encoded video frames, the client can determine motion areas and perform bilinear interpolation only for those sections of the image where motion is detected, and otherwise perform a concatenation of the received static pixel values ​​over a limited sequence of decimated video frames.
