Correlation between oil content and DN values


Image Processing
Image processing in this study used graphic mask operation and multi plane histogram. Graphic mask operation objective is to get the value of DN within the fruit excluding the external area. This analysis gives an accurate DN value of the samples that was used because it eliminates shadows and objects that are not related to this study

Results

Chemical Analysis

A chemical analysis was done to determine the amount of oil content in the oil palm fruit. The results from the lab chemical processing of these three different kinds of fruit is shown in Table 2
