Real-time hardware implementation of multi-resolution image blending

A novel real-time implementation of a multi-resolution image blending algorithm is presented in this paper. A multi-resolution decomposition of the input is used to blend multiple images at different scales. Processing time is shortened by designing a pipeline system. The proposed solution requires less hardware multipliers and is able to achieve very high operating frequencies, compared to the current designs. The presented hardware architecture is optimized to support multiple simultaneous video streams, and high frame rates at High-Definition (HD) resolutions.
