Main Article Content
This article presents strawberry ripeness classification by support vector machine (SVM). Three groups strawberry including over ripeness, ripeness and un-ripeness are determined. Strawberry image is captured using low-resolution camera of 640 x 480 pixels. The histogram graph of HSV color model is used for feature extraction. To train the SVM, 150 strawberry samples are employed and 75 samples are used for testing. The result shows that the average accuracy of the SVM prediction of 97.3% is achieved. Therefore, this proposed system is suitable to use and develop for agriculture.
