متن کاملMatching Deformable Features Based on Oriented Multi-scale Filter Banks
This paper presents a technique to enable deformable objects to be matched throughout video sequences based on the information provided by multi-scale Gaussian derivative filter banks. We show that this technique is robust enough for viewpoint changes, lighting changes, large motions of the matched object and small changes in rotation and scale. Unlike other well-known color-based techniques, t...
متن کاملBandwidth Efficient Filter Banks for Transmultiplexers
This thesis addresses the problem of simultaneously transmitting several data signals across a single channel. For this purpose, a transmultiplexer that uses modulated filter banks is studied. Modulated filter banks comprise filters that are bandpass versions of a lowpass prototype. The filters serve to assign portions of the channel bandwidth to the data signals. The impulse responses of the f...
متن کاملEfficient Implementation of Complex Modulated Filter Banks Using Cosine and Sine Modulated Filter Banks
The recently introduced exponentially modulated filter bank (EMFB) is a 2M-channel uniform, orthogonal, critically sampled, and frequency-selective complex modulated filter bank that satisfies the perfect reconstruction (PR) property if the prototype filter of an M-channel PR cosine modulated filter bank (CMFB) is used. The purpose of this paper is to present various implementation structures f...
متن کاملEfficient implementation of complex exponentially-modulated filter banks
In Exponentially-Modulated Filter Bank (EMFB) the complex subfilters are generated from a real-valued prototype filter by multiplying the filter impulse response with complex exponential sequences. This gives the possibility to use block transforms with computationally fast algorithms. Our definition for the EMFB is based on Extended Lapped Transform (ELT). Then we may apply Fast ELT based algo...
