Rgbexcel: an Rgb Image Data Extractor and Exporter for Excel Processing
نویسنده
چکیده
The objective of this paper was to develop a means of rapidly obtaining RGB image data, as part of an effort to develop a low-cost method of image processing and analysis based on Microsoft Excel. A simple standalone GUI (graphical user interface) software application called RGBExcel was developed to extract RGB image data from any colour image files of any format. For a given image file, the output from the software is an Excel file with the data from the R (red), G (green), and B (blue) bands of the image contained in different sheets. The raw data and any enhancements can be visualized by using the surface chart type in combination with other features. Since Excel can plot a maximum dimension of 255 by 255 pixels, larger images are downscaled to have a maximum dimension of 255 pixels. Results from testing the application are discussed in the paper.

Morphological Exudate Detection in Retinal Images using PCA-based Optic Disc Removal
Diabetic retinopathy lesion detection such as exudate in fundus image of retina can lead to early diagnosis of the disease. Retinal image includes dark areas such as main blood vessels and retinal tissue and also bright areas such as optic disk, optical fibers and lesions e.g. exudate. In this paper, a multistage algorithm for the detection of exudate in foreground is proposed. The algorithm se...
متن کاملAn Effective Image Demosaicking Algorithm with Correlations among RGB Channels
In this paper, an effective image demosaicking algorithm, which is based on the correlation among the three primary colors, is proposed for mosaic image with Bayer color filter array (CFA). To reduce the distortion and improve the reconstruction quality, the proposed interpolation method makes full use of the brightness information and the edge information. We design several filters with size o...
متن کاملPredicting Cut Rose Stages of Development and Leaf Color Variations by Means of Image Analysis Technique
The monitor and prediction of crop developmental stages, particularly harvest time, play an important role in planning greenhouse cropping programs and timetables by cut rose producers. There have been many scientific reports on the application of image analysis technology in estimating greenhouse crop growth stages. In the present research, we studied leaf color variations over time by taking ...

In this paper, we propose a method of classification of image by combining wavelet transform and neural network. Our main objective in this work is to achieve an optimal approach of classification by combining wavelet transform and neural network. The proposed scheme for successful classification is combination of a wavelet domain feature extractor and back propagation neural networks (BPNN) cl...
متن کاملNuclear Image Analysis Study of Neuroendocrine Tumors
BACKGROUND There is a subjective disagreement about nuclear chromatin in the field of pathology. Objective values of red, green, and blue (RGB) light intensities for nuclear chromatin can be obtained through a quantitative analysis using digital images. METHODS We examined 10 cases of well differentiated neuroendocrine tumors of the rectum, small cell lung carcinomas, and moderately different...
