开源中国的 IT 公司开源软件整理计划介绍
Dlib 18.15 发布,此版本更新内容如下:
新特性
- Added a number of tools for working with 3D data:
- Added the perspective_window which is a tool for displaying 3D point clouds.
- Added camera_transform. It performs the 3D to 2D mapping needed to visualize 3D
data.
- Added point_transform_affine3d as well as functions for creating such transforms:
rotate_around_x(), rotate_around_y(), rotate_around_z(), and translate_point().
- Added draw_solid_circle() for drawing on images.
- Added get_best_hough_point() to the hough_transform.
- Thanks to Jack Culpepper, the python API for object detection now outputs detection
confidences.
- Added lspi, an implementation of the least-squares policy iteration algorithm.
非向后兼容特性
- The shape_predictor and shape_predictor_trainer had a non-optimal behavior when used
with objects that have non-square bounding boxes. This has been fixed but will cause
models that were trained with the previous version of dlib to not work as accurately if
they used non-square boxes. So you might have to retrain your models when updating dlib.
Bug 修复
- Fixed a bug which prevented add_image_rotations() from compiling.
其他改进
- The imglab tool now allows the user to click and drag annotations around by holding
shift and right clicking.
Dlib是一个使用现代C++技术编写的跨平台的通用库,遵守Boost Software licence.
