What are the limitations of technology for general object recognition in images?

One limitation of technology for general object recognition in images is the difficulty in accurately identifying objects with complex shapes or textures. To improve this, one approach is to use deep learning techniques such as convolutional neural networks (CNNs) which can learn hierarchical features from images to better recognize objects.

// Example code implementing object recognition using a pre-trained CNN model
// Load a pre-trained CNN model for object recognition
$model = new CNNModel('path/to/pretrained_model');

// Load an image to be recognized
$image = loadImage('path/to/image.jpg');

// Use the CNN model to predict the object in the image
$prediction = $model->predict($image);

// Output the predicted object label
echo 'Predicted object: ' . $prediction;
