WinDIAS

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

• Rapid, inexpensive, true colour image analysis
• Advanced Leaf Area Meter features
• Automated measurement of diseased and healthy leaf areas
• Simple, powerful colour picking
• Conveyor accessory for rapid processing of leaves

What it does

The WinDIAS system uses a PC with an image grabber card to offer fast image analysis for a wide range of applications. It provides a full set of measurement statistics, and can process up to 800 leaves per hour with the conveyor option.

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

WinDIAS is especially suited to applications that need high colour discrimination, for example in plant pathology; it can also count objects in an image.

The basic WinDIAS system includes a high resolution colour CCD video camera and a powerful image grabber card. A lightbox and overhead lighting unit ensure good contrast and colour rendition. WinDIAS software runs on a Pentium 133 or higher PC.

WinDIAS features

Editing: Using the mouse, images can be edited on-screen to retouch boundaries, separate objects that overlap, remove undesirable "noise" and holes, add or erase lines, rectangles and polygons, and fill bounded areas in any user-specified colour.

Measurement: WinDIAS analyses the thresholded regions to measure the following parameters: area, perimeter, length, width, circularity, elongation and shape factor.

Calibration is carried out against a ruler. Where projected area has to be used to estimate the surface area (of pine needles for example) a correction factor can be applied.

Object count: Seeds, needles, or other small objects can be quickly counted by WinDIAS. Colour 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 stores and uses images in 24-bit colour TIF format. Results can be transferred to other Windows applications, such as Excel, stored on file, and printed out in formatted reports.

WinDIAS accepts images from many sources, such as CCD video cameras, video recorders, and images stored on computer media. Zoom An optional zoom lens kit permits fields of view down to 5 mm across, without the need for a microscope.
