An Efficient Motion Adaptive De-interlacing and Its VLSI Architecture Design

Abstract: This paper presents an efficient motion adaptive deinterlacing technique that consists of two main steps, i.e. 4-field extended Gaussian filtering motion detection and adjustable window ELA de-interlacing. Four consecutive interlaced fields are used to detect motion accurately. With a Gaussian filter, the motion detection can eliminate the influence of noise. An adjustable window ELA de-interlacing is adopt to process motion pixels, which can reconstruct image with high quality even in areas with horizontal ed… Show more

“…Indeed, we report a higher frame rate by a factor of 9.2 for the 480i format, due mainly to added instruction-level parallelism made possible by the pipeline and to a larger bus. In fact, our architecture also achieves a frame rate/gates ratio that is comparable to that of a recent custom ASIC implementation of a low-complexity motion-adaptive algorithm based on a modified version of ELA [13].…”

“…The unified interpolator is dynamically reconfigured in performing the correct interpolation as determined by the motion, edge, and spectrum content analyzers. On the contrary, the content analyzers are required SCD [27] EMA [28 at the same time in the worst case. Therefore, no reconfiguration is applied to these functionalities.…”

“…The proposed deinterlacing algorithm is compared to two algorithms, deinterlacing with scene change detection (SCD) [27] and efficient motion adaptive deinterlacing [28]. These two algorithms target at high-definition (HD) deinterlacing and provide VLSI designs for comparison.…”

“…With the popularity of progressive-scanned display devices and the wide application of advanced video algorithms based on the frame data, interlaced-scanned video sequences need to be turned into progressive-scanned video sequences in order to solve the display problems caused by different scanning format and make up for incomplete information caused by the lack of anther field data [1][2] . Motion-adaptive de-interlacing algorithm (MA) has a relatively small amount of calculation and can effectively reduce the hardware cost, is suitable for the application of the embedded video surveillance systems [3][4] . While traditional motion-adaptive de-interlacing algorithm improves inefficiently the vertical resolution of the motion region, what is more if there are some faster spatially-periodic patterns moving in a video field sequence it is easy to appear the moving virtual image [5] .…”
