Abstract

Homomorphic filter approach for image processing is very well known as a way for image dynamic range and increasing contrast. According to this approach, input signal is assumed to consist of two multiplicative components: background and details. The standard problem in processing such signals involves logarithm operation, division on two components by implementing low frequency and high-pass filters, addition of evaluations multiplied by different gain coefficients, and exponent calculation. In this paper we propose to use median filter for deriving multiplicative component evaluations. It was found that the proposed homomorphic filter has several useful properties in remote sensing image enhancement applications. Experimental results for simulated and real image processing are presented in the paper.
