Physical quality determination of fresh strawberry (Fragaria x ananassa var. Osogrande) fruit in tropical environment using image processing approach

Strawberry (Fragaria x ananassavar.Osogrande) fruit has a high economic value and healthy for human. However, there was a problem with strawberries quality for supply chain and can be deteriorated easily during the transportation process, especially in tropical environment. Image processing is one of the methods considered to be applied for rapid detecting using non-destructive method. Objective of this research was to compare the determination of physical quality of strawberry fruit between conventional method and image processing method. Determination of the image processing method was using webcam 8 mp with 100 maturity level of strawberry fruit, then after acquisition of the sample of strawberry the data was analysed using Matlab software. Observations of the physical quality parameters observed including color and texture of skin, diameter, length, volume and the surface area of strawberries. Performance of image processing have relatively good, with high accuracy for several physical quality of strawberry fruit such as : length (96,50), diameter (93,70), Area (93,88), volume (96,42), texture (83,8) redness (a∗) (76,74) and yellowness (b∗) (66,89) with not significant difference with conventional method measurements, however (lightness (L∗) color parameter significant difference between image processing and conventional measurements.
