WinDIAS provides high speed measurement and analysis of leaf area and leaf features, making it the ideal tool for plant pathology applications.

The WinDIAS system offers specialized image analysis features suitable for a wide range of applications in the plant sciences. It is specially suited to applications that need high color discrimination, for example in plant pathology. It provides a full set of measurement statistics, and can process up to 800 leaves per hour using the conveyor belt option. The WinDIAS components include a choice of high resolution color USB video cameras with a lightbox and overhead lighting rig to ensure good contrast and color rendition, or alternatively an A4 scanner with excellent depth of field.

For reporting and further analysis, all results and images from WinDIAS are easily exchanged with other Windows applications.

Rapid thresholding: Three thresholds can be set, each based on a different user-defined range of colors. The primary threshold is used for the main zones of interest in the image, e.g. healthy areas. The secondary and tertiary thresholds are used for other zones, e.g. diseased areas. Thresholds are set by a simple point and click with the mouse in a region of interest. The areas included are immediately visible as overlays on the image.

Editing: Images can be edited on-screen to retouch boundaries, separate objects that overlap, remove undesirable "noise" and holes, add or erase lines or rectangles, and fill bounded areas in any color.

Measurement: WinDIAS analyzes the thresholded regions to measure area, perimeter, length, width, circularity, elongation and shape factor. A correction factor can be applied to estimate the surface area (of pine needles for example) from the projected area. Calibration is carried out against a ruler.

Object count: Seeds, needles, or other small objects can be quickly counted by WinDIAS. Color thresholding enables easy discrimination of different types of object, or disease spots. Dust and debris can be excluded by defining a minimum object area.

Exchange of data and images: WinDIAS imports images in .bmp, .jpg and .tif formats, and results can be saved as .txt files for easy import into Excel.
