By using this code, when I show the image of the object in a phone it tracks its name but when i show a video then it can not identify the object, what's wrong in the code. I think I am going wrong in the third line i-e (snapshot(camera)). Please help me what to add or remove in this code.
camera = webcam; % Connect to the camera
load("trained filename")
im = snapshot(camera); % Take a picture
image(im); % Show the picture
im = imresize(im,[224 224]); % Resize the picture for alexnet
label = classify(netTransfer,im); % Classify the picture
title(char(label)); % Show the class label

snapshot gets a frame from a camera. If you want to read from a video you need to call VideoReader. See some attached demos.
