Обнаружение детей-гуманоидов: методы и примеры кода

Чтобы определить, является ли ребенок гуманоидом, вы можете использовать различные методы в зависимости от используемого вами языка программирования или платформы. Вот несколько примеров на разных языках:

  1. Python (с использованием библиотеки PyTorch):

    import torch
    from torchvision.models import resnet50
    def is_child_humanoid(image_path):
    # Load pre-trained ResNet50 model
    model = resnet50(pretrained=True)
    # Set the model to evaluation mode
    model.eval()
    # Load and preprocess the image
    image = Image.open(image_path)
    preprocess = transforms.Compose([
        transforms.Resize(256),
        transforms.CenterCrop(224),
        transforms.ToTensor(),
        transforms.Normalize(mean=[0.485, 0.456, 0.406], std=[0.229, 0.224, 0.225]),
    ])
    input_tensor = preprocess(image)
    input_batch = input_tensor.unsqueeze(0)
    # Move the input to the GPU if available
    device = torch.device("cuda" if torch.cuda.is_available() else "cpu")
    input_batch = input_batch.to(device)
    # Perform the inference
    with torch.no_grad():
        output = model(input_batch)
    # Get the predicted label (here assuming index 0 represents humanoid)
    _, predicted_idx = torch.max(output, 1)
    label = predicted_idx.item()
    # Return True if the predicted label is 0, indicating a humanoid
    return label == 0
  2. JavaScript (с использованием TensorFlow.js):

    import * as tf from '@tensorflow/tfjs';
    import * as mobilenet from '@tensorflow-models/mobilenet';
    async function isChildHumanoid(imageElement) {
    // Load the MobileNet model
    const model = await mobilenet.load();
    // Preprocess the image
    const image = tf.browser.fromPixels(imageElement);
    const processedImage = tf.image.resizeBilinear(image, [224, 224]);
    const batchedImage = processedImage.expandDims(0).toFloat().div(127.5).sub(1);
    // Perform the inference
    const predictions = await model.classify(batchedImage);
    
    // Get the predicted label (here assuming index 0 represents humanoid)
    const label = predictions[0].className;
    // Return true if the predicted label contains the word "humanoid"
    return label.toLowerCase().includes('humanoid');
    }
  3. Java (с использованием библиотеки Deeplearning4j):

    import org.datavec.image.loader.NativeImageLoader;
    import org.deeplearning4j.nn.graph.ComputationGraph;
    import org.deeplearning4j.nn.modelimport.keras.KerasModelImport;
    import org.nd4j.linalg.api.ndarray.INDArray;
    public class HumanoidDetector {
    private static final String MODEL_PATH = "path/to/model.h5";
    public static boolean isChildHumanoid(String imagePath) throws Exception {
        // Load the Keras model
        ComputationGraph model = KerasModelImport.importKerasModelAndWeights(MODEL_PATH);
        // Load and preprocess the image
        NativeImageLoader loader = new NativeImageLoader(224, 224, 3);
        INDArray image = loader.asMatrix(imagePath);
        image.divi(255); // Normalize pixel values
        // Perform the inference
        INDArray[] output = model.output(false, image);
        // Get the predicted label (here assuming index 0 represents humanoid)
        int predictedLabel = output[0].argMax().getInt(0);
        // Return true if the predicted label is 0, indicating a humanoid
        return predictedLabel == 0;
    }
    }
