or use single-shot detection (SSD). You can train a custom object detector, or use a pretrained object detector by leveragingtransfer learning, an approach that enables you to start with a pretrained network and then fine-tune it for your application. Convolutional neural networks require Deep ...
As we know, image classification is probably the most common use for deep neural network in computer vision. Most of the CNN networks are designed to extract features from images which can be later used to recognize it. This lead to an intuitive strategy for object detection: the region based...
CNN(convolutional neural network)在目标检测中大放异彩,R-CNN系列,YOLO,SSD各类优秀的方法层出不穷。在2D图像的目标检测上,不少学术界提出的框架已经投入商用。但是,具体落实到自动驾驶、机器人这类应用场景上时,2D场景下的目标检测对于3D真实世界的场景描述依然不够。 目标检测问题实际上包含了两个任务:定位和分类。
《Rich feature hierarchies for Accurate Object Detection and Segmentation》这篇文章的算法思想又被称之为:R-CNN(Regions with Convolutional Neural Network Features),是物体检测领域曾经获得state-of-art精度的经典文献。 这篇paper的思想,改变了物体检测的总思路,现在好多文献关于深度学习的物体检测的算法,基本上都...
The processing circuitry may use a predicted mask and a real mask to learn a convolutional neural network system. The real mask includes first pixels corresponding to the real boundary and second pixels corresponding to a fake boundary adjacent to the real boundary.Hyunku Lee...
There are a huge number of features which are said to improve Convolutional Neural Network (CNN) accuracy. Practical testing of combinations of such features on large datasets, and theoretical justification of the result, is required. Some features operate on certain models exclusively and for certai...
