Determination of the damage level of two-spotted spider mite (Tetranychus urticae Koch.) using image processing technique

In the present study, The number of two spotted spider mites (Tetranychus urticae) on cucumber leaf and the dameges which they caused were determined by using image processing algorithms. The leaves images were taken with the camera placed on platform which is designed and produced by us. For this purpose, 10 leaf images with different levels of damage were taken and processed by using image processing technique using MATLAB Image Processing Toolbox module. As a result of the study, has been detemined the percentage of damage on leaves obtained at different levels; a: %20.68, b: %31.42, c: %35.13, d: %52.42, e: %57.68, f: %81.98, g: %86.73, h: %87.76, i: %87.87, j: %95.79 mite count results obtained by observation; a: 48, b: 88, c: 92, d: 102, e: 128, f: 38, g: 27, h: 26, i: 21, j: 13.
