Comparing Image Format and Resolution for Assessment of Foliar Diseases of Wheat

K. Steddom, M. McMullen, B. Schatz, and C. M. Rush

May 2005

Research

The authors have investigated the effect of image resolution and format on lesion area quantification with image analysis. Image format had little effect on the results and image resolution did not affect results until the image resolution had dropped below the level at which it was difficult to discern lesions by eye. This suggests that low-resolution digital cameras with high JPEG compression levels are suitable for plant disease measurement using image analysis.
