Navigating hours of video material is often time-consuming, and traditional keyframe displays are not particularly useful when studying single-shot studio recordings of music-related movement. This paper presents the idea of motiongrams and how we use such displays in our studies of dancers’ free move-

Tracking a camera’s movement through space while compiling a map of the observed environment, commonly called Simultaneous Localization And Mapping (SLAM), is a central task in robotics and computer vision. Many variants of this task exist, depending on the available sensor data, whether it has to run at interactive rates or with offline data, and the desired properties of the resulting scene m...

We present a novel keyframe-based global localization method for markerless real-time camera tracking. Our system contains an offline module to select features from a group of reference images and an online module to match them to the input live video for quickly estimating the camera pose. The main contribution lies in constructing an optimal set of keyframes from the input reference images, w...

The ability to localise a camera moving in a previously unknown environment is desirable for a wide range of applications. In computer vision this problem is studied as monocular SLAM. Recent years have seen improvements to the usability and scalability of monocular SLAM systems to the point that they may soon find uses outside of laboratory conditions. However, the robustness of these systems ...

A keyframe summary, or “static storyboard”, is a collection of frames from a video designed to summarise its semantic content. Many algorithms have been proposed to extract such summaries automatically. How best to evaluate these outputs is an important but little-discussed question. We review the current methods for matching frames between two summaries in the formalism of graph theory. Our an...

Animasi 3D merupakan salah satu penerapan ilmu grafika komputer. Film animasi dapat digunakan sebagai media pembelajaran untuk menyampaikan pesan. Dalam perancangannya, masih banyak film yang menghasilkan gerakan kaku dan tidak realistis. Hal ini disebabkan karena terdapat kekurangan pada proses animating. Masalah tersebut melatarbelakangi penelitian ini. Tujuan ingin dicapai adalah menemukan m...

When using deep learning networks for dynamic feature rejection in SLAM systems, problems such as a priori static object motion leading to disturbed build quality and accuracy slow system runtime are prone occur. In this paper, based on the ORB-SLAM2 system, we propose method improved YOLOv5 combined with geometric constraint methods map building environments. First, paper uses ShuffleNetV2 lig...

In traditional animation, keyframes are modeled and standard graphics pipeline is used to animate the scene. In this paper we consider volume animation where the 30 world and its components are represented as a voxel model. The voxel model is annotated with hierarchical feature information and thus facilitates easy volume editing. These annotations are based on regularised Minkowski operators u...

3D-keyframe animation is a popular method for animating articulated gures. It allows artistic expressiveness by providing control to the animator. The drawback of this process is that it requires signi cant e ort from the animator. Recently, work has focused on high level techniques such as adapting reference movements. However, whatever the way the animation is produced, the nal process is an ...
