Aiming at the problems of low detection accuracy for objects with non-significant features in FCOS network, a new object method based on attention mechanism is proposed to improve performance which can effectively guide network focus detailed features. According verification experimental results KITTI dataset, AP value improved mechanism-based car and person by 1.1% 4.9% compared standard respe...

This paper presents the correlation-based motion estimation technique for 3D displacement of objects. Two high-speed cameras are configured as a stereovision system and synchronized in real-time. Finger hand motions captured form digital images at 1500 fps 2000 respectively. A complete acquisition is calibrated to determine intrinsic extrinsic parameters which were later used correlation algori...

This study is a contribution to assess the high resolution digital aerial imagery for semi-automatic analysis of tree species identification. To maximize the benefit of such data, the object-based classification was conducted in a mixed forest plantation. Two subsets of an UltraCam D image were geometrically corrected using aero-triangulation method. Some appropriate transformations were perfor...

To extract region features independent on translation, rotation and scaling of object, a new coordinate system is established. The origin of the new coordinate system can be set at the mass center of the object. The new axis ' x and ' y are based on the main inertia axes. The size of the object can be identified by its minimal constraint rectangle called feature rectangle which has minimal area...

We present a procedure for tracking a rigid object based on a piecewise planar model, and show how it can be used to track a human face. The tracking is performed using a single incremental SSDbased tracker. The main feature of the approach presented is that it can track a rigid set of arbitrarily small patches all of which could not be individually tracked.

In this paper a novel two-stage architecture for object-based segmentation of moving sequences is proposed using multiple features such as motion, intensity and texture. The first stage locates perceptually meaningful objects using a hierarchy of single-feature segmentation processes. The second stage refines the boundaries of located objects using a combination of features according to a set o...

Zusammenfassung Neben einer hohen Kompressionseffizienz und einer guten Fehlerrobustheit stellt MPEG-4 Video als einziger internationaler Standard objektbasierte Funktionalitäten für Anwendungen zur Verfügung. In diesem Beitrag werden die Ziele und Techniken der MPEG-4 objektbasierten Kodierung beschrieben. Summary MPEG-4 is the first international standard that supports applications with objec...
