Dlib 18.15 发布,跨平台 C++ 通用库

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.

主要特点如下:

1.完善的文档:每个类每个函数都有详细的文档,并且提供了大量的示例代码,如果你发现文档描述不清晰或者没有文档,告诉作者,作者会立刻添加。

2.可移植代码:代码符合ISO C++标准,不需要第三方库支持,支持win32、Linux、Mac OS X、Solaris、HPUX、BSDs 和 POSIX 系统

3.线程支持:提供简单的可移植的线程API

4.网络支持:提供简单的可移植的Socket API和一个简单的Http服务器

5.图形用户界面:提供线程安全的GUI API

6.数值算法:矩阵、大整数、随机数运算等

7.机器学习算法:

8.图形模型算法:

9.图像处理:支持读写Windows BMP文件,不同类型色彩转换

10.数据压缩和完整性算法:CRC32、Md5、不同形式的PPM算法

11.测试:线程安全的日志类和模块化的单元测试框架以及各种测试assert支持

12.一般工具:XML解析、内存管理、类型安全的big/little endian转换、序列化支持和容器类
