Abstract: The disclosure provides a noise filter. The noise filter includes a motion estimation (ME) engine. The ME receives a current frame and a reference frame. The current frame comprising a current block and the reference frame includes a plurality of reference blocks. The ME engine generates final motion vectors. The current block comprises a plurality of current pixels. A motion compensation unit generates a motion compensated block based on the final motion vectors and the reference frame. The motion compensated block includes a plurality of motion compensated pixels. A weighted average filter multiplies each current pixel of the plurality of current pixels and a corresponding motion compensated pixel of the plurality of motion compensated pixels with a first weight and a second weight respectively. The weighted average filter generates a filtered block. A blockiness removal unit is coupled to the weighted average filter and removes artifacts in the filtered block.

Abstract: A device includes an input array register, a determining component and a computing component. The input array register stores a sorted list of n elements as an input array having size n, n being an integer greater than or equal to two. The determining component creates a list of m elements as a mask array having a size m, m being an integer greater than or equal to one, one of the m elements being based on two adjacent of the n elements of the input array. The computing component performs a mathematical operation between the input array and the mask array to generate a list of p elements as an output array having a size p, p being an integer greater than or equal to 0, the p elements identifying unique elements within the n elements.

Abstract translation: 一种设备包括输入阵列寄存器，确定组件和计算组件。 输入阵列寄存器存储n个元素的排序列表作为大小为n的输入阵列，n是大于或等于2的整数。 确定组件创建m个元素的列表作为具有尺寸m，m是大于或等于1的整数的掩模阵列，m个元素中的一个基于输入阵列的n个元素中的两个相邻。 计算组件在输入阵列和掩模阵列之间执行数学运算，以产生p个元素的列表作为具有大小p，p为大于或等于0的整数的输出阵列，p元素标识该元素内的唯一元素 n元素。
