Abstract :
Filtering is widely used in image and video processing for various applications. Recently, the guided filter has been proposed and became one of the popular filtering methods. In this paper, to achieve the computation demand of guided filtering in full-HD video, a double integral image architecture for guided filter ASIC design is proposed. In addition, a reformation of the guided filter formula is proposed, which can prevent the error resulted from truncation in the fractional part and modify the regularization parameter ε on user´s demand. The hardware architecture of the guided image filter is then proposed and can be embedded in mobile devices to achieve real-time HD applications. To the best of our knowledge, this paper is also the first ASIC design for guided image filter. With a TSMC 90-nm cell library, the design can operate at 100 MHz and support for Full-HD (1920 × 1080) 30 frame/s with 92.9K gate counts and 3.2 KB on-chip memory. Moreover, for the hardware efficiency, our architecture is also the best compared to other previous works with bilateral filter.
