Features extraction based on the Discrete Hartley Transform for closed contour
In this paper the authors propose a new closed contour descriptor that could be seen as a Feature Extractor of closed contours based on the Discrete Hartley Transform (DHT), its main characteristic is that uses only half of the coefficients required by Elliptical Fourier Descriptors (EFD) to obtain a contour approximation with similar error measure. The proposed closed contour descriptor provid...
متن کاملDiscrete Hartley transform based multicarrier modulation
This paper presents a real-valued discrete multicamer modulation approach that is based on the use of the discrete Hartley transform (DHT) and its inverse (IDHT) to perform the modulation and demodulation operations. Since the DHT and IDHT definitions are identical, we can use the same hardware or program to implement the modulator and demodulator of the proposed multicarrier method. As compare...
متن کاملA Fragile Watermarking Based on Separable Discrete Hartley Transform for Color Image Authentication (fwsdhtcia)
In this paper, a fragile watermarking based on two-dimensional Separable Discrete Hartley Transform has been proposed for color image authentication (FWSDHTCIA). Two dimensional SDHT is applied on each 2 × 2 sub-image block of the carrier image in row major order and produces four frequency components in transform domain. Due to the high sensitivity of human eye on green channel, only one authe...
متن کاملA Factorization Scheme for Some Discrete Hartley Transform Matrices
Discrete transforms such as the discrete Fourier transform (DFT) and the discrete Hartley transform (DHT) are important tools in numerical analysis, signal processing, and statistical methods. The successful application of transform techniques relies on the existence of efficient fast transforms. In this paper some fast algorithms are derived. The theoretical lower bound on the multiplicative c...
متن کاملAn Analytical Approach for Efficient OFDM Modulator and Demodulator Communication Systems Based On Discrete Hartley Transform
The main drawback of OFDM is its high peak to average power ratio (PAPR). High PAPR of OFDM makes it unusable in non-linear systems. So the clipping signals scheme is one useful and simple method to reduce the PAR. In the widely used OFDM (Orthogonal Frequency Division Multiplexing) systems, the FFT and IFFT pair are used to modulate and demodulate the data constellation on the subcarriers. Thi...
