1. Channel Setup

The color image of 128 × 128 px obtained earlier through data split has the advantage of being easy to identify the characteristics of the data in the form of three channels. However, since there are three channels of data, the size of the data is large, which limits the number of learning data and the implementation of deep neural networks, this study has transformed the data into black and white image data to conduct learning (see Table 3).
