YOLO / SSD / DenseBox 等方法;以及最近出现的结合RNN算法的RRC detection;结合DPM的Deformable CNN等 本文重点介绍类别2和3中的方法。上述分类参考文献[1]。 基于候选区域生成+深度学习分类的方法 这类方法的一个前提是需要算法先计算出候选区域(Bounding Boxes),之后是把候选区域交给由深度学习为主的分类模型做分类。
很多目标检测技术都会涉及候选框(bounding boxes)的生成,物体候选框获取当前主要使用图像分割与区域生长技术。区域生长(合并)主要由于检测图像中存在的物体具有局部区域相似性(颜色、纹理等)。目标识别与图像分割技术的发展进一步推动有效提取图像中信息。1)滑动窗口通过滑窗法流程图可以很清晰理解其主要思路:首先对输入图像...

Bounding-box regression is a popular techniqueto refine or predict localization boxes in recent object detection approaches. Typically, bounding-box regressors are trained to regress from either region proposals or fixed anchor boxes to nearby bounding boxes of a pre-defined target object classes. ...
使用sliding window search 在一个image上进行 position,scale和aspect ratio上的查找bbox,在可能含有一个object的区域,会产生更多的bounding boxes和更密集地聚集。利用IoU去筛选,refinement,去合并bounding box。最后是对得到的bounding boxes进行NMS,得到最终的sorted boxes。
The subject disclosure relates to techniques for inserting of bounding boxes around image objects. A process of the disclosed technology can include steps for receiving, from a first data set, an image comprising a first image object, processing the image to identify a pixel region associated with...
