Finding color range (HSV) manually using GColor2/Gimp tool/trackbar manually from a reference image which contains a single fruit (banana) with a white background. Therefore, we used a method to increase the accuracy of the fruit quality detection by using colour, shape, and size based method with combination of artificial neural network (ANN). Above code snippet is used for filtering and you will get the following image. It was built based on SuperAnnotates web platform which is designed based on feedback from thousands of annotators that have spent hundreds of thousands of hours on labeling. It would be interesting to see if we could include discussion with supermarkets in order to develop transparent and sustainable bags that would make easier the detection of fruits inside. .masthead.shadow-decoration:not(.side-header-menu-icon):not(#phantom) { We use transfer learning with a vgg16 neural network imported with imagenet weights but without the top layers. Our test with camera demonstrated that our model was robust and working well. Interestingly while we got a bigger dataset after data augmentation the model's predictions were pretty unstable in reality despite yielding very good metrics at the validation step. A simple implementation can be done by: taking a sequence of pictures, comparing two consecutive pictures using a subtraction of values, filtering the differences in order to detect movement. Then, convincing supermarkets to adopt the system should not be too difficult as the cost is limited when the benefits could be very significant. Cadastre-se e oferte em trabalhos gratuitamente.
