چکیده

This article proposes a flexible tracker which can estimate motions and deformations of 3D objects in images by considering their appearances as nonrigid surfaces. In this approach, a flexible model is built by matching local features (key-points) over training sequences and by learning the deformations of a spline based model. A statistical model captures the variations of object appearance caused by 3D pose variations. Visual tracking is then possible, for each new frame, by matching the local features of the model with the image features, according to their local appearances and the constraints provided by the flexible model. This approach is demonstrated on real-world image sequences.

Planning and Control of Two-Link Rigid Flexible Manipulators in Dynamic Object Manipulation Missions

This research focuses on proposing an optimal trajectory planning and control method of two link rigid-flexible manipulators (TLRFM) for Dynamic Object Manipulation (DOM) missions. For the first time, achievement of DOM task using a rotating one flexible link robot was taken into account in [20]. The authors do not aim to contribute on either trajectory tracking or vibration control of the End-...

Moving Objects Tracking Using Statistical Models

Object detection plays an important role in successfulness of a wide range of applications that involve images as input data. In this paper we have presented a new approach for background modeling by nonconsecutive frames differencing. Direction and velocity of moving objects have been extracted in order to get an appropriate sequence of frames to perform frame subtraction. Stationary parts of ...

3D Models Recognition in Fourier Domain Using Compression of the Spherical Mesh up to the Models Surface

Representing 3D models in diverse fields have automatically paved the way of storing, indexing, classifying, and retrieving 3D objects. Classification and retrieval of 3D models demand that the 3D models represent in a way to capture the local and global shape specifications of the object. This requires establishing a 3D descriptor or signature that summarizes the pivotal shape properties of th...

Tracking 3D pose of rigid objects using Inverse Compositional Active Appearance Models

This paper presents a method for tracking the 3D pose of rigid objects. The proposed method is a 3D extension of the appearance-based approach called Active Appearance Models (AAM). Here, the 3D shape of the object and the geometry of the camera are added as part of the minimizing parameters of the AAM algorithm in order to determine the full 6 degree-of-freedom (DOF) pose of the object. This w...
