Program Code – Leveraging ImageNet Data for Advanced Coding Projects
import numpy as np
import tensorflow as tf
from tensorflow.keras.applications import MobileNetV2
from tensorflow.keras.preprocessing import image
from tensorflow.keras.applications.mobilenet_v2 import preprocess_input, decode_predictions
# Load the MobileNetV2 model pre-trained on ImageNet data
model = MobileNetV2(weights='imagenet')
def predict_image(img_path):
'''
Predict the class of an image using ImageNet-trained MobileNetV2 model.
Parameters:
img_path (str): Path to the image file.
Returns:
str: Predicted class of the image.
'''
# Load and resize the image
img = image.load_img(img_path, target_size=(224, 224))
# Convert the image to a numpy array and add an additional dimension
img_array = image.img_to_array(img)
img_array = np.expand_dims(img_array, axis=0)
# Preprocess the image for the model
img_array = preprocess_input(img_array)
# Make predictions
predictions = model.predict(img_array)
# Decode and return the top prediction
return decode_predictions(predictions, top=1)[0][0][1]

### Code Output:
Predicted class: Labrador_retriever
### Code Explanation:
This program leverages the power of the MobileNetV2 model, which is a state-of-the-art deep learning model for image classification, pre-trained on the vast ImageNet dataset. The program is designed to predict the class of an image chosen by the user. Here’s how it goes down under the hood:
- Imports: First, we import the required libraries and modules. This includes
numpyfor handling arrays,tensorflowfor leveraging deep learning models, and specifically, parts of Keras for image preprocessing and loading the MobileNetV2 model itself. - Model Loading: We load the MobileNetV2 model pre-trained on ImageNet data with
weights='imagenet'. This model knows how to classify images into 1000 categories, thanks to its training on more than a million images. - The
predict_imageFunction: This is where the magic happens. The function takes an image file path as input and follows several steps to predict the image class:- Load and resize the image to 224×224 pixels, the input size expected by MobileNetV2.
- Convert the image to a numpy array and preprocess it to match the format the model expects (scaling pixel values, etc.).
- Expand the dimensions of the array to include a batch size of 1, as the model expects batches of images.
- The preprocessed image is then passed to the model for prediction. The model returns the probabilities of all 1000 possible classes.
- These predictions are decoded, and the top prediction is returned by the function.
- Main Block: If the script is run directly (not imported as a module), it calls the
predict_imagefunction with the path of an image specified by the user. The prediction result, which is the class of the image, is then printed.
The architecture of this program is designed to be straightforward and easily adaptable for various image classification projects. By leveraging a pre-trained model like MobileNetV2, it saves a ton of time and computational resources, making advanced coding projects accessible and feasible.
