Rich feature hierarchies for accurate object detection and semantic segmentation

by Ross Girshick, Jeff Donahue, Trevor Darrell, Jitendra Malik
"... Object detection performance, as measured on the canonical PASCAL VOC dataset, has plateaued in the last few years. The best-performing methods are complex en-semble systems that typically combine multiple low-level image features with high-level context. In this paper, we propose a simple and scala ..."

in order to localize and segment objects and (2) when labeled training data is scarce, supervised pre-training for an auxiliary task, followed by domain-specific fine-tuning, yields a significant performance boost. Since we combine region proposals with CNNs, we call our method R-CNN: Regions with CNN

Supervised learning of semantic classes for image annotation and retrieval

by Gustavo Carneiro, Antoni B. Chan, Pedro J. Moreno, Nuno Vasconcelos - IEEE Transactions on Pattern Analysis and Machine Intelligence , 2007
"... Abstract—A probabilistic formulation for semantic image annotation and retrieval is proposed. Annotation and retrieval are posed as classification problems where each class is defined as the group of database images labeled with a common semantic label. It is shown that, by establishing this one-to- ..."

and extensive experiments. The supervised formulation is shown to achieve higher accuracy than various previously published methods at a fraction of their computational cost. Finally, the proposed method is shown to be fairly robust to parameter tuning. Index Terms—Content-based image retrieval, semantic image

Self-Tuning Semantic Image Segmentation

by Sergey Milyaev, Olga Barinova
"... Abstract. In this paper we present a method for finding optimal parameters of graph Laplacian-based semantic segmentation. This method is fully unsupervised and provides parameters individually for each image. In the experiments on Graz dataset the accuracy of segmentation obtained with the paramete ..."

Fully convolutional networks for semantic segmentation

by Jonathan Long, Evan Shelhamer, Trevor Darrell , 2014
"... Convolutional networks are powerful visual models that yield hierarchies of features. We show that convolu-tional networks by themselves, trained end-to-end, pixels-to-pixels, exceed the state-of-the-art in semantic segmen-tation. Our key insight is to build “fully convolutional” networks that take ..."

classification networks (AlexNet [17], the VGG net [28], and GoogLeNet [29]) into fully convolu-tional networks and transfer their learned representations by fine-tuning [2] to the segmentation task. We then de-fine a novel architecture that combines semantic informa-tion from a deep, coarse layer

Locating tune changes and providing a semantic labelling of sets of Irish traditional tunes

by Cillian Kelly, Mikel Gainza, David Dorran, Eugene Coyle, Dit Kevin St - Proceedings of the International Symposium on Music Information Retrieval , 2010
"... An approach is presented which provides the tune change locations within a set of Irish Traditional tunes. Also provided are semantic labels for each part of each tune within the set. A set in Irish Traditional music is a number of individual tunes played segue. Each of the tunes in the set are made ..."

The piece of music consists of segments called tunes, and each tune consists of further segments called parts. 1.

Weakly Supervised Semantic Segmentation with Convolutional Networks

by Pedro O. Pinheiro, Ronan Collobert
"... We are interested in inferring object segmentation by leveraging only object class information, and by consider-ing only minimal priors on the object segmentation task. This problem could be viewed as a kind of weakly super-vised segmentation task, and naturally fits the Multiple In-stance Learning ..."

, by adding only few smoothing priors. Our system is trained using a subset of the Imagenet dataset and the segmentation experiments are performed on the challenging Pascal VOC dataset (with no fine-tuning of the model on Pascal VOC). Our model beats the state of the art results in weakly supervised object

A Comparison of Geometric and Energy-Based Point Cloud Semantic Segmentation Methods

by Mathieu Dubois, Paola K. Rozo, Fabio A. González O, David Filliat
"... Abstract—The recent availability of inexpensive RGB-D cameras, such as the Microsoft Kinect, has raised interest in the robotics community for point cloud segmentation. We are interested in the semantic segmentation task in which the goal is to find some relevant classes for navigation, wall, ground ..."

SEMANTIC LABELING OF TRACK EVENTS USING TIME SERIES SEGMENTATION AND SHAPE ANALYSIS

by Josh Harguess, J. K. Aggarwal
"... This paper presents a novel framework for applying semantic labels to events within a track. A track is a two-dimensional (2D) or a three-dimensional (3D) signal in time where each point of the signal is the x and y (and z) centroid spatial coordinate of an object at a specific frame of the video. T ..."
