调用其它组件中成员 通过GameObject(游戏物体). Base class for all entities in Unity scenes.  是Unity场景里面所有实体的基类. 可以理解为两个类间的访问,定义一个超类用其中一个类实现. 默认的gameObject为当前组件.transform为变换,有常用属性position(Vector3三维向量). 熟记transform下属性和方法作用. transform.translate() 平移,给定vector3,给定坐标系'物体坐标…

一.How to make auto-adjustments(brightness and contrast) for image Android Opencv Image Correction i'm using OpenCV for Android. I would like to know,how to make image correction(auto adjustments of brightness/contrast) for image(bitmap) in android vi…

BACKGROUND The present invention relates to video processing systems. Advances in imaging technology have led to high resolution cameras for personal use as well as professional use. Personal uses include digital cameras and camcorders that can captu…

基本思想 通过Dlib获得当前人脸的特征点,然后通过旋转平移标准模型的特征点进行拟合,计算标准模型求得的特征点与Dlib获得的特征点之间的差,使用Ceres不断迭代优化,最终得到最佳的旋转和平移参数. 使用环境 系统环境:Ubuntu 18.04 使用语言:C++ 编译工具:CMake 第三方工具 Dlib:用于获得人脸特征点 Ceres:用于进行非线性优化 CMinpack:用于进行非线性优化 (OPTIONAL) 源代码 https://github.com/Great-Keith/head…

概括 通过Dlib获得当前人脸的特征点,然后通过旋转平移标准模型的特征点进行拟合,计算标准模型求得的特征点与Dlib获得的特征点之间的差,使用Ceres不断迭代优化,最终得到最佳的旋转和平移参数. Android版本在原理上同C++版本:头部姿态估计 - OpenCV/Dlib/Ceres. 主要介绍在移植过程中遇到的问题. 使用环境 系统环境:Ubuntu 18.04 Java环境:JRE 1.8.0 使用语言:C++(clang), Java 编译工具:Android Studio 3.4.…

这个模型思想很直观(有误),但是写的源码太难懂了(看的是release-3的版本,最接近Object Detection with Discriminatively Trained Part Based Models论文的实现)其实相似的论文还有一篇8页的A Discriminatively Trained, Multiscale, Deformable Part Model,建议先看8页的.参考博客1的格式,结合源码写写我对论文的理解(不一定对). Introduction 1.We desc…

1 综述 Separating touching objects in an image is one of the more difficult image processing operations. The watershed transform is often applied to this problem. The watershed transform finds "catchment basins"(集水盆) and "watershed ridge line…
