RGBEXCEL : An RGB Image Data Extractor and Exporter for Excel Processing

摘要

The objective of this paper was to develop a means of rapidly obtaining RGB image data, as part of aneffort to develop a low-cost method of image processing and analysis based on Microsoft Excel. A simplestandalone GUI (graphical user interface) software application called RGBExcel was developed to extractRGB image data from any colour image files of any format. For a given image file, the output from thesoftware is an Excel file with the data from the R (red), G (green), and B (blue) bands of the imagecontained in different sheets. The raw data and any enhancements can be visualized by using the surfacechart type in combination with other features. Since Excel can plot a maximum dimension of 255 by 255pixels, larger images are downscaled to have a maximum dimension of 255 pixels. Results from testing theapplication are discussed in the paper.
