摘要： A method and system converts a binary image into an analog image by first tagging pixels that are part of edges in the digital image and using this tagging information to eliminate such tagged pixels from the digital filtering process. The elimination of such tagged pixels from the digital filtering process substantially eliminates artifacts near the edges, thereby reducing any distraction from the perceived quality of the output image.

摘要： Realistic ultrasound imaging simulation requires modeling of scatterers corresponding to different imaging speckle appearances. A scatterer generator acquires a plurality of ultrasound signal samples, each corresponding to a different ultrasound capture and reconstructs a scatterer representation from the ultrasound signal samples and associated Point Spread Functions. Point Spread Functions (PSFs) may be estimated from multiple image acquisitions at the same reference position resulting from beam-steering. Reconstructed scatterers may then directly be used in ultrasound simulation or an additional step of modeling the scatterers may be applied. Statistical distribution parametrization or texture synthesis may be used to model the scatterers. Different scatterer models may be used for different homogeneous regions. The reconstructed scatterers and/or the scatterer models may be registered into a library of scatterers by the scatterer generator.

摘要： An image processing method is provided. The method is configured to process the color-block image output by the image sensor. The face region of the color-block image is determined. A part of the color-block image beyond the face region is converted into a first simulation image using a first interpolation algorithm. A part of the color-block image within the face region is converted into a second simulation image using a second interpolation algorithm. The complexity of the second interpolation algorithm is less than that of the first interpolation algorithm. The first simulation image and the second simulation image are merged into a simulation image corresponding to the color-block image. An image processing apparatus and an electronic device are provided. With the image processing method, the image processing apparatus and the electronic device, distinguishability and resolution of the image are improved, and time required for processing the image is reduced.
