A Leaf Area Meter,

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 area, morphology and disease analysis. Different configurations are offered in function of measurements, speed, accuracy and portability.


Components of a WinFOLIA System
Image Acquisition Hardware
When portability is not required, we recommend WinFOLIA systems based on high resolution desktop scanners. These devices produce high quality images free of illumination problems (such as non-uniform lighting). Unlike cameras, scanners have a built-in permanent calibration and are very easy to use. We sell different models in function of their scan area (the maximum leaf size they can digitize), speed and accuracy.

Note: Desktop scanners cannot be used in the field but are transportable and usable in remote locations where electrical power is available.

Our lightweight portable scanner can be used for in the field leaf image acquisition. Non-destructive acquisition, while leaves are attached to the plant, is a possibility. It takes its power from a portable computer or a tablet running Windows 8 (or 7) and allows WinFOLIA to get images directly from it to do in field leaf analysis. It has a very good image quality and ease of use.
Portable Imaging & Calibration Kit (PICK)

Conventional and inexpensive digital cameras1 can also be used for leaf image acquisition (in the field or laboratory). 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 (needles, roots, ...) in fields with a camera for their analysis in Regent's programs (WinFOLIA, WinSEEDLE, WinCAM, ...). The latter can be done in field or in laboratory.

It contributes in different ways to obtaining good images suitable for precise automated analysis. The background provides good contrasts with biological samples. The translucent non-reflective cover holds them firmly against it to avoid shadows and distorted measurements. Calibration targets allow to make a fast and precise calibration in just one click (to get measurements in units of your choice (mm, cm...).

The camera is held above it using a tripod (not included) with or without an extension arm and uses the ambient light (it works under sunny or cloudy days). To avoid fuzziness due to the depress of the shutter we recommend to trigger the camera using a remote control (an option for many camera models) or, if your camera is WiFi, using a phone or tablet.

It comes in 3 sizes (to accomodate larger or more leaves per image) and two models. One is optimized for color and morphology analysis (disease quantification, area per color, leaf or object area...) using the Pro version of Regent's software, the other for more basic leaf (or object) area and morphology analyses (grey levels analysis) using any of its software.

The PICK is a good complementary item to our scanner based systems wich works in the office (they are more precise and produce higher definition images).

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

The LAK comes in various sizes:
• 30 x 40 cm (12" x 16")
• 45 x 60 cm (18" x 24")
• 70 x 90 cm (24" x 36")
