The recently upgraded WinDIAS 3 Leaf Image Analysis System provides fast, accurate measurement of leaf area and leaf features – making it ideal for plant pathology and phenotyping applications. WinDIAS’s analysis features are well suited to applications where precise colour discrimination is critical.

 

Entry Level System	Standard System	Rapid System
Throughput (leaves/hour)	~50 (typical, depends on leaf size)	~150	~800
Resolution	Typically >1000 dpi	2048 x 1536 pixels	1280 x 1536 pixels
Minimum object size	~ 0.02 mm	1 pixel	1 pixel
Maximum sample area	297 x 210 mm (A4)	300 x 295 mm	250 x 290 mm (conveyor) 250 x >1000 mm (long leaf mode)
Accuracy area measurement [1]	± 1% typical	± 4% typical	± 4% typical
Accuracy diseased/healthy area	contrast dependent	contrast dependent	contrast dependent
Accuracy long leaf mode	not applicable	not applicable	± 5% typical
Calibration static measurements	against an object of known length, e.g. a ruler		against a ruler
Calibration conveyor measurements	not applicable		against a target of known area
Conveyor belt speeds	not applicable	not applicable	60/100/140/190 mm/s (20% faster for 60Hz model)
Colour depth	WinDIAS works in 24bit colour space (16 million colours)
Image file formats	.jpg, .bmp and .tif (WinDIAS is compatible with many scanners and cameras that are TWAIN compliant)
Operating system and drivers	Windows 7, 8 and 10 (32 and 64 bit)

Specification apply to a WinDIAS system using standard components supplied by Delta-T Devices. Use of other cameras, lighting systems or camera stands may reduce accuracy due to reflections, poor contrast, or image distortion.
