Abstract:
In this paper, we propose a novel method for satellite image restoration. This method base on high boost filter. The least square error condition is applied to optimize the boost coefficient of the high boost filter. Boost coefficient is arranged in an analytic form. Then its value can be computed directly from the formula. Thailand Earth Observation System (THEOS) panchromatic images are used to test the proposed method to retrieve original scenes. Modulation Transfer Function (MTF), Signal to Noise Ratio (SNR) and National Imagery Interpretability Rating Scale (NIIRS) are considered for image quality comparisons. The experimental results show that this method is superior to the traditional filter, e.g. Weiner filter, both vision and image quality metrics.
