| Resumo | The image restoration problem attempts to recover image that has been degraded by the limited resolution of the sensor as well as by the presence of noise. The resolution of images obtained by the satellite sensors is degraded by sources such as: optical diffraction, detector size and electronic filtering. As a consequence, the effective resolution is, in general, worse than the nominal resolution, that corresponds to the detector projection on the ground and does not take into consideration the sensor imperfections. Through restoration techniques, it is possible to improve image resolution up to a certain level. Fonseca et al. (1993)have presented a methodology to restore images taken from Landsat-5 Thematic Mapper (TM). The idea is to use the same method for restoring images taken from Landsat-7 TM (ETM+). For this purpose, we have done an evaluation of the effective spatial resolution (EIFOV)of the ETM+ images that has been presented in this paper. The imaging system model of the ETM+ sensor is discussed, as well as the factors that contribute to the degradation of its spatial resolution. For each band of the ETM+, the EIFOV parameter is calculated. Using this information and modeling the ETM+ modulation transfer function as a gaussian, some preliminary results of ETM+ image restoration are presented. The restoration algorithm is based on the method of the transfer function compensation that approximates the filter inverse and at the same time attempts to control the problems associated with it. This article also shows that the restoration process combined with the resampling process can generate interpolated ETM+ images with better visual quality than the images interpolated by parametric cubic convolution. |
