Once the neural network has been trained, sample the entire image as 5x5 images, flatten the images and test the neural network on the flattened images. Networks train for strictly image classification cannot be directly used for object detection to predict the bounding box around an object in an image. This code trains a CNN using a collection of facial images that are cropped and aligned. And training Convolutional Neural Network alexnet by modifying output layers by number of subjects. As you progress in the exercises you can use MATLAB help command to display the help of the. 5 than there was a cat in the image otherwise not. According to the Neural Network toolbox, I can use the command genFunction to generate a Matlab function that simulate the trained neural network and then use codegen to generate a C/C++ code. Convolutional neural networks are an important class of learnable representations applicable, among others, to numerous computer vision problems. AlexNet in MATLAB, Deploy on Nvidia Jetson TX2. It would be helpful. It depends on exactly what form (file type, label markers, etc) it is in. This demo uses AlexNet, a pretrained deep convolutional neural network that has been trained on over a million images. For classification accuracy, I use the Minimum Correct Classification Rate (MCCR). Anyway, the mcr is always about 15%. Very Simple Image Classification Application using Web Cam. I have a hyper-spectral data of wavelength range 400-1000nm.
