For broad leaf analysis

A Leaf Area Meter,

Leaf Morphology Analyser &

Disease and Insect Damage Quantifier

WinFOLIA is a computer image analysis system that accurately do morphological measurements on broad leaves. It comprises hardware for image acquisition (scanner or digital camera and accessories) and a computer program, WinFOLIA, specifically designed for leaf analysis (area, morphology and disease analysis). Different configurations are offered in function of measurements, speed, accuracy, portability and cost.

The WinFOLIA software program is very easy to use. To get an image from a scanner, simply click the scanner icon and specify the scan area size. After the scan, the image is displayed in WinFOLIA's Image area, ready to be analysed. A simple click on the image is all that is required for basic analyses (like area, length and wdith). More complex analyses require another click at the petiole-blade junction.


Components of a WinFOLIA System
Image Acquisition Hardware
WinFOLIA systems are based on scanners, but can also work with images from cameras (see below). These produce high quality images, free of illumination problems (such as non-uniform lighting) and are extremely easy to use. Unlike cameras, scanners have a built-in permanent calibration, so the user does not have to calibrate their images, neither have to adjust their lighting system. We sell different models in function of their scan area (the maximum leaf size they can digitize), speed, accuracy and portability.
Portable Imaging & Calibration Kit (PICK)

Conventional and inexpensive digital cameras1 can also be used for leaf image acquisition. Precautions must be taken so that calibration can be done accurately and rapidly. To facilitate this task, we offer the Portable Imaging & Calibration Kit (PICK) for digital cameras.

The PICK allows to acquire images of leaves and other biological samples with a camera in fields, for analysis with our software programs (WinFOLIA, WinSEEDLE, WinCAM, ...). The latter can be done in field or in laboratory (recommended). It contributes in different ways to obtaining good images suitable for precise automated analysis; 1) The background provides good contrasts with the biological samples, 2) The translucent non-reflective cover holds them firmly against it to avoid shadows and distorted measurements, and 3) Calibration targets allow to make a fast and precise calibration in just one click or in somes cases automatically. Calibration is required to get measurements in units of your choice (mm, cm...).

It is offered in two different sizes and comes with two backgrounds. One is optimized for color and morphology analysis (disease quantification, area per color, leaf or object area...) using the Pro version, the other for more basic leaf area and morphology analyses (grey levels analysis).

The camera is held above the PICK using a tripod (not included) with or without an extension arm and can use the ambient light or a diffuse light (not included). To avoid fuzziness due to the depress of the shutter we recommend to trigger the camera using its timer or a remote control.

The PICK is a good complementary item to our scanner based systems.

1 Almost any model can be used. We do not sell or recommend digital cameras.
