摘要：
An algorithm for centroid Detection in an imageComprising: (a) acquiring an image of Wavefront XXY size represented by a pixel Signal Intensity variable that contains a Plurality of spots (b) to compress the image of F.You Wave size XXY an image of size n and X \/ X \/ m where M is equal to n, any integer and X \/ nAnd M are integer values (c) identify a background Intensity to any position in the compressed Image and subtracting this background from the compressed Image (d) identify a Plurality of centroidApproximately positioned in the compressed Image taken from that comprises: a) determine the maximum value of signal in Image dB) establish a Threshold Value as a default rateYoure done the maximum DC) determining a position X, a position, andAnd Signal intensity of each pixel that has a Signal Intensity greater than the Threshold Value (dd) sort the values of the step (c) in descending order of Signal intensity of attached)R the highest Signal Intensity as the first centroid approximately positioned and DF) to select a preset condition to define all the values sorted as centroids from salBody positioned, which are the pre condition.Where the pre condition is that the position of each centroid is Post positioned approximately at a distance further than a fixed distance from the centroidS already determined (e) iterate STEP (d) until you find the approximate positions of a Plurality of desired centroids (f) to convert the approximate position of PluralityCentroids in desired positions in the image more accurate Wavefront size XXY, so each position of the centroid in the image has been identified.Un algoritmo para la detección de centroides en una imagen, que comprende: a) adquirir una imagen de frente de onda de tamaño XxY representada por una intensidad de señal de píxel variable que contiene una pluralidad de manchas b) comprimir la imagen de frente de onda de tamaño XxY a una imagen de tamaño X/n x Y/m, donde n, m es igual a cualquier número entero y X/n, Y/m so
