Abstract: A coil component includes a body having one surface, and one end surface and the other end surface, respectively connected to the one surface and opposing each other, a support substrate embedded in the body, and a coil portion disposed on the support substrate and including first and second lead-out patterns respectively exposed from surfaces of the body. The first lead-out pattern is exposed from the one surface of the body and the one end surface of the body. The second lead-out pattern is exposed from the one surface of the body and the other end surface of the body. The body includes an anchor portion disposed in each of the first and second lead-out patterns.

Abstract: An improved block noise elimination method is provided, which uses one-dimensional pixel vectors made of pixel rows or columns across two neighboring blocks to analyze blocky noise residing across the neighboring blocks. The blocky noise in each pixel-vector is modeled as shape vector multiplied by boundary discontinuity. The shape vector, varying with local image activity, is estimated by Minimum Mean Squared Error (MMSE) approach. Depending upon the shape vector, the corresponding blocky noise is eliminated in postprocessing of decoded images so that encoded images may be restored to their original images.
