![]() ![]() For LH and HL sub-bands, two algorithms work together in order to preserve regularity. The offered method has a multi-faceted approach for the problem by sub-band coding, it handles each 2D-DWT image sub-band with a different solution. ![]() ![]() The purpose of this method is to consider two contrasting issues of over-smoothing and creation of spurious edges at the same time, and offer a novel solution based on statistical dependencies of image sub-bands, and noise behavior. This paper proposes a novel method for the image interpolation problem based on two-dimensional discrete wavelet transform (DWT) with the edge preserving approach. ![]() Compared to existing prominent DCT processors, the proposed processor achieves better results with limited hardware resources. Furthermore, due to the shared-resource implementation of CORDIC-II unit, by reduction of adding, shifting operations both in size, and number, the processor has high capabilities in short word lengths in comparison with state-of-the-art DCT processors. The processor has a low-complexity and distributed controller. Inputs and outputs of the processor are in-order which can be taken into account as an advantage for the proposed design. Using one processing element, the memory-based architecture has reduced the power consumption. To reduce the resources, and utilization area all micro-rotation operations have implemented as one united block in overlapped form. The micro-rotation section of the architecture is based on a shared-resource improved coordinate rotation digital computer (CORDIC) unit, in an enhanced scalable DCT engine. This paper proposes a new discrete cosine transform (DCT) processor. ![]()
