| description | Cyanobacteria can be used as indicators to offer relatively exclusive information pertaining
to ecosystem condition. Cyanobacteria react quickly and predictably to a broad range of
pollutant. Thus provides potentially constructive early caution signals of worsening
environment and the possible causes. Therefore the aim of this study is to develop an image
processing and pattern recognition methods to detect and classify oscillatoria genus from
Cyanobacteria found on tropical Putrajaya Lake (Malaysia). Computer-based image
analysis and pattern recognition methods were used to construct a system that is able to
identify, and classify selected Cyanobacteria genus automatically. An image analysis
algorithm was implemented to contrast, filter, isolate and recognize objects from
microscope images. Image preprocessing module used to contrast images, to remove the
noise, and to improve image quality. Segmentation module used to isolate the different
objects found in input image. A combination of Feed forward artificial neural network
(ANN) with feature extraction module was used to train and recognize oscillator images.
System accuracy was measured by using manual and automated classifying methods, and
developed system showed a great accuracy system reach to 90%. |
