    摘要: Provided are a multiplierless FIR digital filter and a method of designing the same, in which a filtering operation is performed by a small addition/subtraction circuit using extracted information after analyzing the property of a given coefficient and extracting information required for design by only adding/subtracting operations. In the method of designing the multiplierless FIR digital filter, tables are created to extract and store information needed for adding and subtracting operations. An addition table is created to store values obtained by adding the input data synchronized with a clock frequency. Further, a value corresponding to multiplication is obtained by performing extraction and error correction on the added values from the tables, and an adder chain of an output terminal sums up the values and outputs the filtering results, thereby effectively implementing a logic circuit of the multipliedess FIR digital filter.

    摘要: An anisotropic diffusion method and apparatus based on the direction of an edge are disclosed. In the anisotropic diffusion apparatus, directional pattern masking is performed to determine the direction of an edge in an image including noise, and values obtained through the directional pattern masking are convoluted to calculate the magnitude of an image. If the calculated magnitude value of the edge is larger than a threshold value, the edge of the image is preserved, while if the calculated magnitude value of the edge is not larger than the threshold value, noise cancellation is strengthened, whereby noise can be effectively canceled (or concealed) while preserving the edge representing the characteristics of the image, and thus, an image of high quality can be obtained.
