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

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

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

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

locations and semantic part labels. Figure 1. A representation of the structure present within a piece of Irish Traditional music. There are two distinct hierarchical levels of segmentation. The piece of music consists of segments called tunes, and each tune consists of further segments called parts. 1.

, 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

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

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
