Objects selection and recognition during remote sensing images digital processing by means of LabVIEW

Abstract

The article discusses the possibility of using the image processing module of the LabVIEW modeling system from National Instruments for the optical aerial and satellite images digital processing. The objects recognition and selection in the images is quite time-consuming process and requires a significant time investment with the involvement of highly qualified experts. In order to automate the object recognition process, the virtual instruments have been developed for converting multi-zone images into a pseudo-color image, as well as for decoding color and pseudo-color images. A method of identifying objects belonging to the specified classes based on replacing a color image with a grayscale and its subsequent binarization is proposed. Based on this method, the virtual instruments have been developed to automate the process of selecting objects and determining their geometric characteristics.
