Latest Patents

One of Reid's latest patents is titled "Image encoding with dynamic buffer-capacity-level-based compression adjustment." This patent describes methods, systems, and computer programs for encoding images. In this innovation, quantized frequency domain vectors are generated from a sequence of image blocks. Each vector includes quantized forward transform coefficients derived from the respective image block. The current input capacity level of a buffer is determined for each successive vector, and modifications are made to increase compressibility when the capacity level is below a prescribed threshold. The modified and unmodified vectors are then encoded into a sequence of image blocks stored in the buffer.

Another notable patent is the "System and method for digital image tone mapping using an adaptive sigmoidal function based on perceptual preference guidelines." This patent introduces an adaptive image tone mapping curve generated as a sigmoidal function. The parameters of the sigmoidal function are determined by original image statistics, ensuring that the tone mapping process does not drastically alter the image histogram shape. The calculation of the sigmoidal tone curve is efficient, utilizing simple arithmetic operations and pre-calculated factors.
