[!--:en--]In this topic we will keep an updated list of the next planned improvements for Samantha. The list is ordered by priority. If you would like to ask for new features or improvements, please do it

Major features currently in development:
- Keypoint Extractor / Descriptor. We are developing our own keypoint robust extractor. (Released with version 1.10)
- Improved autocalibration (Released with version 1.20)
- Local/lazy bundle adjustment. This will be very helpful with very large datasets (Released with version 1.30).
- 32 Bit support (Released with version 1.40) [!--:--][!--:it--]In this topic we will keep an updated list of the next planned improvements for Samantha. The list is ordered by priority. If you would like to ask for new features or improvements, please do it

We have just released version 1.1 of Samantha.[br /]
This is the first version that makes use of our novel proprietary keypoint extractor / descriptor. From our tests we are performing slightly better than SIFT. Running times are also slightly worse than SIFT. The code is not fully optimized but it makes already use of CUDA in some parts (where available).[br /]
Here is the full change list:[br /]
- Novel Scale-Space robust keypoint extractor and descriptor.[br /]
- Multicore ANN stage ( + Speed ).[br /]
- Minor fixes in Multimatching ( + Robustness ).[br /]
- Improved clusterization ( + Speed ).[br /]
- Fixed a bug on MSE computation.[br /]
- Minor Bundle Adjustment improvements ( + Robustness ).[br /]
[br /]
Any feedback is more than welcome!

We have released a small fix for samantha 1.11 Version.[br /]
Here is the list of changes from v.1.1:[br /]
- Fixed a bug in KeypointDensity property[br /]
- Fixed a minor bug in descriptor computation[br /]
- Added the possibility to switch multithreading o during ANN computation[br /]

3DFSamantha 1.20 has been just released![br /]
Big improvements have been made on the autocalibration routines.[br /]
Here is the full list of changes from the previous version:[br /]
- Major improvements on autocalibration and variable intrinsics bundle adjustment.[br /]
- Optional tangential radial distortion coecient Adjustment.[br /]
- Novel two-Step autocalibration technique.[br /]
- Minor x on keypoint descriptor computation near the images border.[br /]
- The maximum number of keypoints (KeypointMaxN parameter) forces the keypoints to span as more image area as possible.[br /]
- Points triangulation speed improvements.[br /]
- Paths management and default settings changed.

3DFSamantha 1.30 has been released![br /]
Two new Major features have been added ( Conservative Bundle Adjustment and Point Recovery strategy ) and several minor fixes.[br /]
Here is the full list of changes:[br /]
- Lazy/Conservative bundle adjustment (global speed improvements on the geometric reconstruction phase).[br /]
- Novel Point Recovery Strategy (improvements on global robustness).[br /]
- Exterior fitting procedure changed ( using Procrustean algorithm instead of Fiore ).[br /]
- Final Point Cloud cleanup heuristic added.[br /]
- Minor fixes and improvements on projective pipeline.[br /]
- Autocalibration is now the default choice in settings.

3DFSamantha 1.40 released.[br /]
Here is the full changelog:[br /]
- Added 32 bit support.[br /]
- Improved keypoint extraction and description (robustness and accuracy improved).[br /]
- The KeypointDensity and KeypointMaxN parameters have been removed and have been substituted with KeypointMeanN, i.e. the mean number of keypoint to extract for each image. The extraction process has became a bit slower, but more stable.[br /]
- Faster matching phase.[br /]
- Fixed a bug in the two step reconstruction (accuracy improved).[br /]
- Fixed a bug in two views triangulation (robustness improved).[br /]
- Image undistortion is now skipped if no distortion is present (improved speed).[br /]
- Fixed a crash during ANN computation.[br /]
- Added exporter for the bundler v3 format.

- Changed server connection settings for the online updater.[br /]
- Updated to the last version of the external library Eigen.

[Roberto]

v.1.50 released.
