This letter presents a high-performance architecture of a novel first-order polynomial convolution interpolation for digital image scaling. A better quality of interpolation is achieved by using higher order model that requires complex computations. The kernel of the proposed method is built up of first-order polynomials and approximates the ideal sinc-function in the interval [-2, 2]. The proposed...
This paper presents a novel image interpolation method, extended linear interpolation, which is a low-cost architecture with the interpolation quality compatible to that of bi-cubic convolution interpolation. The architecture of reducing the computational complexity of generating weighting coefficients is proposed. Based on the approach, the low-cost hardware architecture with digital image scaling...
This paper presents an efficient VLSI design of bicubic convolution interpolation for digital image processing. The architecture of reducing the computational complexity of generating coefficients as well as decreasing number of memory access times is proposed. Our proposed method provides a simple hardware architecture design, low computation cost and is easy to implement. Based on our technique,...
Video de-interlacing techniques, which convert the format of interlaced images to progressive images, are important today to improve the quality of display. Motion adaptive de-interlacing techniques are capable of improving the quality of the visual results. Most of them focus on the static or horizontal motion detection only; nevertheless, their performances are also affected by vertical motion....
