The basic idea employed is to design the morphological filter using an a priori modeling of the stripes. The overall algorithm is divided in three steps. A binary image showing the high frequencies in the vertical direction is first obtained. Another binary image is then deduced which indicates the location of the stripes. Finally, the corrected image is obtained by morphological interpolation at the stripe location. The effect of each processing step is illustrated from an original image of the Porto Alegre city, south of Brazil, corrupted by the stripes.</p></div>","PeriodicalId":101020,"journal":{"name":"Photogrammetria","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1989-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0031-8663(89)90015-X","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83686147","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It will have 10-nm wide spectral bands from 0.4 to 2.5 μm at 30-m spatial resolution over a 24-km swath. The spectral resolution allows identification of many minerals in rocks and soils, important algal pigments in oceans and inland waters, spectral changes associated with plant canopy biochemistry, composition of atmospheric aerosols, and grain size of snow and its contamination by absorbing impurities. The bands will have 12-bit quantization over a dynamic range suitable for bright targets, such as snow. For targets of low brightness, such as water bodies, image-motion compensation will allow gains up to a factor of 8 to increase signal-to-noise ratios. The sensor will be able to point ±26° crosstrack and +52°/−30° downtrack. In the 705-km orbit altitude proposed for Eos, the crosstrack pointing capability will allow 3–4 views during a 16-day revisit cycle.</p></div>","PeriodicalId":101020,"journal":{"name":"Photogrammetria","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1989-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0031-8663(89)90013-6","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75283846","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hence, the paper models can be conveniently used to model the sea surface undulations. The main results of the present laboratory study are: The frequency of a sinusoidal surface is best estimated when the camera angle is about 45° and the illumination angle is also 45°. Clear skylight illumination produces more accurate estimates than those obtained with diffused illumination. The amplitude of the sinusoidal surface must be less than one third (<span><math><mtext>1</mtext><mtext>3</mtext></math></span>) of its wavelength so that no higher harmonics are generated and the spectral peak height is proportional to the waveheight.</p><p>Finally, this study verifies through laboratory model studies some of the theoretical conclusions previously reported using order theory.
