IMPLEMENTACIÓN DE UN CORRELADOR DE IMÁGENES USANDO LA TRANSFORMADA DE FOURIER FRACCIONAL MEDIANTE UN PROCESADOR DIGITAL DE SEÑALES (DSP).

IMPLEMENTATION OF AN IMAGE CORRELATOR USING FRACTIONAL FOURIER TRANSFORM BY A DIGITAL SIGNAL PROCESSOR (DSP).
MSc. Wilson Castaño Galviz, MSc. Yezid Torres Moreno.

Abstrac: In this work we show the use of the Fraccional Fourier Transform on images correlation. Its implementation will be carried out on a DSP (Digital Signal Processor) produced by Texas Instruments, a high capacity and performance equipment allowing to develop calculus at high speed adequated to our necessity of processing. Image correlation will be based on a 4f system or Vanderlught, applying PCE, SNR and OE metrics to analyse this fractional correlator behaviour.

Resumen: La correlación es un método por el cual se pueden detectar objetivos dentro de una señal o imágen dada, puede ser llevada a cabo por dos métodos: óptico y digital, en el trabajo que se va a realizar se centrará en la implementación digital. Se utilizará un DSP (Digital Signal Processor) fabricado por Texas Instruments, el cual es un equipo de alta capacidad y desempeño que permite realizar cálculos a alta velocidad, adecuado para nuestra necesidad de procesamiento. Además el trabajo de correlación se basará en un sistema 4f o de Vanderlught, aplicando las métricas de PCE, SNR y OE para analizar su comportamiento.

Keywords: Correlation, Standard Fourier Transform, Fracctional Fourier Transform, Fast Fourier Transform, Digital Signal Processing (DSP), Signal Processing, Imaging Processing.
