First of all, we would like to share with all of you the pride and excitement following the success of Pleiades launch on Soyouz which took place on saturday the 17th at 03:03 AM CET. To best prepare OTB for these up-coming images, the next OTB release will happen in late january, allowing to test [...]

With the Pleiades launch a few weeks ahead, there has been a lot of ongoing work from the OTB team to prepare for these new data. Since a lot of discussions happened off the list, either with phone meetings, or on other mailing lists (we will see later on why), and since we now have [...]

Processing stereo pairs to derive an elevation map is a very frequent feature request from our users. The otb::FineRegistrationImageFilter has been a first step toward it but it and allows to estimates disparities in a precise way (see for instance this previous post). Yet, there are several steps missing to achieve an elevation (not disparity) map [...]

When processing your images and building up your cutting-edge processing chain with OTB, the need arises to do simple arithmetic operations between the different bands of your images : substracting two bands to study the image differences, threshold the image, apply conditional filtering rule or perform a logarithmic rescaling for example. It requires the use [...]

Local displacements estimation between two images is a common task in many remote sensing applications : DEM extraction, clouds detection … In Orfeo ToolBox, some filters are already available to perform this kind of task, like the otb::NCCRegistrationFilter based on a finite differences method or the otb::DisparityMapEstimationMethod which allows to apply ITK registration framework locally [...]
