Most representative feature for multi class fruit recognition • Color, texture, and shape [Rocha dkk 2010] • Important aspects on building descriptor [Penatti dkk 2012]: • Scalability: the descriptor performance as the size of the collection increase • Diversity: the effect of heterogeneity of the collection to the descriptor effectiveness

Conclusion & Future Works • We presented a combined color and texture feature into a compact descriptor to classify multiclass fruit images with varying pose. • The result proves that our combined descriptor is giving high classification rate.

• Our future work will concentrate on improving classification accuracy with adding shape feature into existing color and texture descriptor on more complicated fruit images. • Further, by increasing the number of category and subcategory of fruit images, we hope the classification rate can be improved.
