What's new in SPRING 5.5.2-5.5.5
Feb 13, 2019
- AUTO AND SEMI AUTOMATIC REGISTRATION OF IMAGES:
- In SPRING version 5.5.2, a new tool for Automatic and Semiautomatic Image Registration has been added. With the use of the Terralib5.2 library, it is possible to use points of interest localization by Moravec or by SURF, also using new Geometric Transformations, such as, "Afinne", "Projective", "RST - (Resampling, Scaling and Translation)" among others. The new registration procedures also make use of Multi-Thread to optimize the location of control points.
- Another utility added in the tool was the validation of image registration information with a positional accuracy measurement of points and features, whose function is to evaluate positioning accuracies through specific sampling points or features. Precision evaluation is done using known trigonometric or statistic functions, such as, RMS (Root Mean Square) deviation, mean, variance, standard deviation, etc..., with absolute or relative values.
New in SPRING 5.5.1 (Feb 13, 2019)
- IMAGE FUSION FOR REMOTE SENSING DATA:
- In SPRING version 5.5.1, the new Image Fusion tool has been added. The Image Fusion tecnique combines the colors of the low-resolution multispectral images with the details of a panchromatic band that has better spatial resolution. The methods added were "IHS Fusion", based on the IHS transform, , " PCA Fusion", based on the Principal Component Analysis transform and the "Wisper Fusion" based on the Wavelet transform.
New in SPRING 5.5.0 (Feb 13, 2019)
- NEW SEGMENTATION PROCEDURES:
- In SPRING 5.5.0 two new segmentation procedures were added:
- The Baatz segmentation of multispectral, multiscale and multiresolution digital images, based on the following scientific article: "An optimization approach for high quality multi-scale image segmentation" by Baatz and Schape, 2000.
- The Baatz segmentation that exploits multi-programming, multithread and multicore features.
- Segmentations of previous SPRING versions have been retained.
- UPDATING, UNIFYING AND COMPATIBILITY WITH THE TERRALIB LIBRARY 5.2:
- For this SPRING 5.5.0 version the new Terralib 5.2 library was updated, unified and compatibility. With this new technology, SPRING can use updated library functions. In order to provide greater integration of the data, the Spring/Terraview-5.2 converter was also updated, allowing data exportation from Spring database projects to new project data patterns using the latest version of the TerraLib 5.2 library.
New in SPRING 5.4.x (Feb 13, 2019)
- SQLSERVER DATABASE MANAGER:
- The SQLSERVER database manager has been incorporated into SPRING.
- The operation of SQLSERVER is similar to SQLITE SGDB. Its main characteristics are:
- * Available for 32- and 64-bit environments;
- * Available for Windows and Linux systems;
- * Does not require installation of a database manager for its use;
- * Has free source code;
- * Has external viewer to access the data tables.
- IMAGE RESTORATION FOR CBERS-4 AND LANDSAT-8 SATELLITE SENSORS:
- Image restoration is a radiometric correction technique whose purpose is to correct the distortions inserted by the optical sensor in the process of generating the digital images. In order to keep SPRING 5.4 up to date, the restore function was modified to process images of the sensors available on the CBERS-4 and LANDSAT-8 satellites.
- BIGTIFF STORAGE FORMAT:
- The TIFF file format uses 32-bit offsets and as such is limited to 4 gigabytes. This has been quite enough for many years. Today however, there is a need for a format for larger image files or very large collections of images, thus breaking the 4 gigabyte limit.
- So, in the SPRING 5.4 was added new Import and Export functions for Tiff and BigTiff image formats. This new formats allow you to use images larger than 4 gigabytes. BigTiff closely resembles TIFF format, but uses 64-bit offsets. The benefits of closely resembling TIFF are enormous, for all properties be inherited and supported in the new version with BigTiff.
- UPDATE OF EXTERNAL LIBRARIES:
- Several external libraries have been updated for the SPRING version 5.4, such as: Libtiff, Libfreetypes, Libjpeg, Libjpeg2000, Libshapefile, Libdxf, Libz, Libqwt and Geosc. In addition to the Qt Toolkit (version 5.7) and the Visual Studio 13 compiler. The TerraLib library has been updated to the latest version and the OGC tool is also in the latest version. Moreover, in the version of Spring 5.4 for Linux, gcc was updated to the most current and the version of Ubuntu is 16.04.
- NEW CUT OUT INFOLAYER FUNCTION:
- In previous versions, the cut out infolayer tool works with a single area, or polygon, in order to trim an infolayer. The 5.4 SPRING version allows to choose various areas (polygons) for this task.
- CSV FORMAT READING:
- It was added importation and exportation functions for tables in CSV (or Comma Separated Values) format. This file format stores tabular data separated by a comma delimiter uses break line to separate values.
- Because they are fairly simple, the .csv files are supported by almost all the spreadsheets and SGDBs available on the market.
