Quickly and easily quantify disease symptoms on plants with Assess 2.0: Image Analysis Software for Plant Disease Quantification. Rapid measurement of leaf area, percent disease, root length, lesion count, percent ground cover, and applications are made simple with this versatile and affordable software. Assess 2.0 introduces automatic measurement (user-independent) of many plant diseases and ground cover, to make disease quantification fast, easy, reliable, and reproducible. Assess 2.0 can also be used as an interactive laboratory tool for real-time length and area measurements of anything that can be imaged (scanned, digital photographs, microscopy, etc.).
The intuitive Windows-based interface makes image analysis and plant disease quantification simple. The program supports Twain-compliant imaging devices such as scanners, frame grabbers, or digital cameras for image acquisition, although images can be imported from any computer drive, CD, network, or other applications. Assess 2.0 supports all standard graphic file formats and most non-standard formats.
Accompanied by a textbook-quality user manual (in pdf format) with nineteen easy-to-follow tutorials, Assess 2.0 makes learning and training fascinating and fun. Automated installation is hassle-free, allowing users to start working on plant disease quantification immediately. Optimized for use in plant pathology and agronomy, this revolutionary tool produces invaluable results for plant pathologists, agronomists, plant breeders, horticultural scientists, and anyone needing to analyze, quantify, and measure plants and plant diseases.
What’s NEW in Assess 2.0?
- Automatic measurement of many plant disease lesions – No matter who measures the disease lesions, the result will always be the same.
- Automatic measurement of ground cover Agronomists and those interested in measuring ground cover can do so with a single click of the mouse.
Automatic recognition and percent-disease measurement of individual leaves on the same image- This new feature is a real time-saver. You can scan many leaves on the same screen and obtain a disease measurement for each leaf with one click of the mouse.
Simple calibration– Images scanned in Assess 2.0 no longer require calibration. Additionally, if the resolution of an image is known (dpi), the user simply enters the values into Assess 2.0. Physical units of measure can now be converted in Assess 2.0. You can calibrate an image in inches and later select one of 10 units without any calibration.
- Support for all standard and many non-standard file formats for reading and writing– Assess 2.0 can handle over 60 file formats, including several RAW formats for digital cameras. No need to convert images using other software.
- Scanner interface
What’s ENHANCED in Assess 2.0?
- Easy and intuitive user interface
- Rapid measurement of area, percent disease, percent ground cover, lesion count, and root length
- Real-time user interactive tool for area, length, and angle measurement
Assess 2.0 can be used as a real-time digital tool for the measurement of area and lengths. This is a very fast way to measure areas of traced objects, lengths of straight lines, or arbitrarily-shaped curves (such as hyphae and roots).
- Image acquisition from any Twain-compliant device including scanners, digital cameras, and frame grabbers
- Simple macro utility and language to automate tasks and perform batch processing
