Passive millimeter-wave image are heavily blurred due to the low-pass filter effect of antenna and the influence of noise. Aimed the problem, an improved method using partial differential equations applied to passive millimeter-wave image high-resolution is proposed. Based on nonlinear bidirectional Laplace filter algorithm, a new passive millimeter-wave image enhancement is proposed. For different...
This paper proposes an edge-adaptive interpolation algorithm for Super-resolution reconstruction. The objective is to recover high-resolution image from low-resolution image. At first, from a low-resolution image, a high-resolution image is formed by bilinear interpolation and its edges are detected. Then, the edge of the original high-resolution image is refined by two approaches: the first is based...
