Special Issue Information

Dear Colleagues,

As remote sensing has witnessed important technological progress with high-definition images, another kind of progress is taking place in the field of satellites, which are able to acquire image time series at high frequency (daily and even multiple times per day). These satellite image time series, also known as SITS, are an important source of information for object classification and scene (e.g., geographic area) understanding. A possible but naive usage of these images would consist in selecting two images from the series and studying their differences and the evolutions they reveal. However, changes in a scene might spread over a long period or even occur in a cycle. Consequently, the number of possible combinations is intractable and cannot be reduced to the analysis of two images. Multisource images have shown promising results and robustness in the recent literature.

In view of the above, ever-expanding choices of multisource satellite images can be considered in object-based classification using image time series. Since multisource satellite images can bring complementary information around the same scene, object-based classification using multisource satellite image time series can achieve increased robustness and accuracy compared with those techniques based on a single or two satellite images. By integrating images from multiple remote sensing sources and including spatial, semantic, and temporal information, object-based classification using multisource image time series becomes a promising research subject. However, this is a challenging task because of variations in spatial information, inconsistency in temporal dimension, abd differences in imaging mechanisms. Therefore, the inclusion of a Special Issue in the journal Remote Sensing is timely to promote innovation and improvement of object-based classification using multisource satellite image time series data. In this Special Issue, we aim to cover the latest advances and trends in the field of multisource satellite image time series.

Multitemporal synthetic aperture radar (SAR) images have been widely used for change detection and monitoring of the environment owing to their competency under all weather conditions. However, owing to speckle backgrounds and strong reflections, change detection in urban areas is challenging. In this study, to automatically extract changed objects, we developed a model that integrated change detection and object extraction in multiple Korean Multi-Purpose Satellite-5 (KOMPSAT-5) images. Initially, two arbitrary L1A-level SAR images were input into the proposed model, and after pre-processing, such as radio calibration and coordinate system processing, change detection was performed. Subsequently, the desired targets were automatically extracted from the change detection results. Finally, the model obtained images of the extraction targets and metadata, such as date and location. Noise was removed by applying scale-adaptive modification to the generated difference image during the change detection process, and the detection accuracy was improved by emphasizing the occurrence of the change. After polygonizing the pixel groups of the change detection map in the target extraction process, the morphology-based object filtering technique was applied to minimize the false detection rate. As a result of the proposed approach, the changed objects in the KOMPSAT-5 images were automatically extracted with 90% accuracy. Full article
