“…Martin and Rybicki [40] used algorithms and a step-wedge or photographic greyscale standard for calibration to allow automation of the image analysis system, enabling the identification of host resistance to maize streak virus in maize, with results superior to visual estimates [72]. Ahmad et al [73] used a colour classifier based on RGB features of symptoms of multiple diseases to grade soyabean seed, with an overall classification accuracy of 88% (which was considered inadequate for the intended purpose). A reliable evaluation of wheat kernels infected with Fusarium culmorum was possible only when the results of both kernel shape and colour analysis were considered [74].…”

Plant disease detection and severity assessment are required for many purposes, including predicting yield loss, monitoring and forecasting epidemics, judging host resistance and for studying fundamental biological host-pathogen processes. If assessments of disease severity are inaccurate and/or imprecise, incorrect conclusions might be drawn and incorrect actions taken. Image analysis based on digital images made using visible wavelengths is one of the several methods used to detect and quantify disease; it offers advantages compared with visual assessment or other methods. Over the last 30 years, major advances have been made to improve reliability, precision and accuracy of image analysis for detecting and measuring plant disease. Although the equipment and software continue to become more sophisticated, these technologies are also becoming easier to use. As a result, image analysis to measure plant disease is becoming increasingly widely used, and has now been applied in the study of numerous plant diseases. This review describes the history, technology and application of visible-wavelength photography and image analysis, and progress towards realizing the full potential of these systems in plant disease detection and assessment RightsWorks produced by employees of the U.S. Government as part of their official duties are not copyrighted within the U.S. The content of this document is not copyrighted.

Plant disease recognition concept is one of the successful and important applications of image processing and able to provide accurate and useful information to timely prediction and control of plant diseases. In the study, the wavelet based features computed from RGB images of late blight infected images and healthy images. The extracted features submitted to Principal Component Analysis (PCA), Kernel Principal Component Analysis (KPCA) and Independent Component Analysis performed (ICA) for reducing dimensions in feature data processing and classification. To recognize and classify late blight from healthy plant images are classified into two classes i.e. late blight infected or healthy. The Euclidean Distance measure is used to compute the distance by these two classes of training and testing dataset for tomato late blight recognition and classification. Finally, the three-component analysis is compared for late blight recognition accuracy. The Kernel Principal Component Analysis (KPCA) yielded overall recognition accuracy with 96.4%.
