AI作画,又称生成艺术、人工智能艺术创作,是指利用人工智能技术,自动生成图像或视频的艺术创作方式。AI作画算法通常基于深度学习技术,通过训练大量图像数据,学习图像的特征和规律,并生成具有相似风格或内容的新图像。
目前主流的AI作画算法主要包括以下几类:
AI作画具有广泛的应用场景,例如:
AI作画算法的实现通常需要以下步骤:
import numpy as np
import tensorflow as tf
from tensorflow.keras import layers
# Define the generator model
def generator_model(latent_dim):
model = tf.keras.Sequential([
layers.Dense(256, activation='relu', input_shape=(latent_dim,)),
layers.Dense(512, activation='relu'),
layers.Dense(1024, activation='relu'),
layers.Dense(7 * 7 * 256, activation='relu'),
layers.Reshape((7, 7, 256)),
layers.Conv2DTranspose(128, (5, 5), strides=(2, 2), padding='same', activation='relu'),
layers.Conv2DTranspose(64, (5, 5), strides=(2, 2), padding='same', activation='relu'),
layers.Conv2DTranspose(3, (3, 3), activation='tanh', padding='same'),
])
return model
# Define the discriminator model
def discriminator_model():
model = tf.keras.Sequential([
layers.Flatten(input_shape=(28, 28, 3)),
layers.Dense(512, activation='relu'),
layers.Dense(256, activation='relu'),
layers.Dense(1, activation='sigmoid'),
])
return model
# Create the generator and discriminator models
generator = generator_model(latent_dim=100)
discriminator = discriminator_model()
# Define the combined model for training
combined_model = tf.keras.Sequential([
generator,
discriminator,
])
# Compile the combined model
combined_model.compile(loss=['binary_crossentropy', 'binary_crossentropy'], loss_weights=[0.5, 0.5], optimizer='adam')
# Prepare the training data
(X_train, _), (_, _) = tf.keras.datasets.mnist.load_data()
X_train = X_train.astype('float32') / 255.0
X_train = X_train.reshape(X_train.shape[0], 28, 28, 3)
# Train the generator and discriminator
for epoch in range(100):
for i in range(100):
# Generate random latent vectors
latent_vectors = np.random.normal(size=(64, latent_dim))
# Generate fake images
generated_images = generator.predict(latent_vectors)
# Create training data for the discriminator
real_images = X_train[i * 64:(i + 1) * 64]
fake_images = generated_images
# Train the discriminator
discriminator_loss_real = combined_model.train_on_batch([real_images, np.ones(64)], [np.ones(64), np.zeros(64)])
discriminator_loss_fake = combined_model.train_on_batch([fake_images, np.zeros(64)], [np.zeros(64), np.ones(64)])
discriminator_loss = (discriminator_loss_real + discriminator_loss_fake) / 2.0
# Create training data for the generator
latent_vectors = np.random.normal(size=(64, latent_dim))
labels = np.ones(64)
# Train the generator
generator_loss = combined_model.train_on_batch([latent_vectors, labels], [labels, labels])
# Print the training progress
print("Epoch:", epoch, "Discriminator loss:", discriminator_loss, "Generator loss:", generator_loss)
# Generate images from random latent vectors
latent_vectors = np.random.normal(size=(10, latent_dim))
generated_images = generator.predict(latent_vectors)
# Display the generated images
for i in range(10):
plt.imshow(generated_images[i] * 255.0, cmap='gray')
plt.show()
