To address it,this study proposed an automatic method to generate training samples from high-resolution night light data,considering that nighttime lights generated by human activities is strongly correlated with impervious surface. First,positive and negative samples for ISA were located according to the distribu‐ tion of nighttime lights. Second,the feature sets were constructed by calculating the spectral and tex‐ ture feature from the OLI images. Third,an ensemble ELM classifier was selected for ISA classifica‐ tion and extraction.

The results show that the proposed method can automatical‐ ly and accurately acquire ISA with an overall accuracy higher than 93% and Kappa coefficient higher than 0. 87. Furthermore,comparative experiments by biophysical composition index(BCI)and classi‐ fication by manual sample were conducted to evaluate its superiority. The results show that our method has better separability for ISA and soil than the BCI. In general,the proposed method is superior to manual methods,except Harbin mostly because some impervious surfaces with weak light intensity are selected as negative samples.","PeriodicalId":50181,"journal":{"name":"红外与毫米波学报","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66394683","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Super-resolution reconstruction of infrared im‐ ages improves image resolution,but at the same time enhances the noise of background. Aiming at this problem,a salience region super-resolution reconstruction algorithm for infrared images based on sparse coding is proposed. By combining the saliency detection and the super-segment reconstruction, it improves the target definition and reduces the background noise. Firstly,image feature is extracted by double-layer convolution,and image patches with large entropy are adaptively selected for training the joint dictionary. Sparse features are used to calculate the saliency to obtain salient regions,which reconstructs image patches in saliency region by the trained dictionary while the background region adopts Gaussian filtering. Experimental results show that the improved reconstruction algorithm is bet‐ ter than ScSR and SRCNN under the same conditions. The image signal-to-noise ratio is increased by 3-4 times.","PeriodicalId":50181,"journal":{"name":"红外与毫米波学报","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66394542","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
