Relationships Between Yield and Crown Disease of Sweet Corn Grown in the Willamette Valley of Oregon

Fig. 1. Examples of sweet corn crown images (inset) and ImageJ grayscale histogram output of the crown region. Stalks were cut longitudinally at the base and scanned on a flatbed scanner. Each pixel of the specified region is measured on a 256-bit grayscale and the histogram is generated using the number of pixels in each grayscale shade. Larger means indicate lighter grayscale values.
