Performance Analysis of ResNet50 and Inception-V3 Image Classification for Defect Detection in 3D Food Printing

Abstract

In the future, 3D food printing may be a fruitful area for the food industry. The presence of this technology opens the public's eyes to a revolution in the food sector, where food processing is limited to the conventional. The existence of this technology will also make food production much more effective and efficient. However, there is a problem when the 3D Food Printing process is carried out; when object defects occur, there will be material waste. This research proposes deep learning-based defect detection for defect and non-defect objects. This model mainly uses CNN as a deep learning method. The dataset is taken from the image of the print process performed at the time of object creation to be trained and validated to check the effectiveness of the proposed model. The architecture used uses pre-trained CNN models namely Inception-V3 and ResNet50 with the hope of classifying images that have a higher viscosity of the material. Where the model has been tested with previous datasets and applied with 3D Food Printing datasets with a dataset division ratio of 85% which is training data and 15% is validation data. After testing the two proposed scenarios, the accuracy result obtained in the test model scenario 1, Inception-V3, is 84.62% and for the test model scenario 2, ResNet50, the accuracy is 93.83%. The outcomes also demonstrate that improved accuracy, loss, and classification time may be obtained by applying CNN in conjunction with data augmentation.
