 Our goal is to accurately classify the source of the image with at least 85% accuracy and achieve at least 80% in the Recall test. 
 
 *Installation instructions*
+
 The following libraries or packages are required: numpy, pandas, tensorflow, keras, matplotlib, sklearn, cv2.  
 We prepare the data for the model by sorted the images into 2 types of folders which are divided equally(real art- labeled as 0, fake art- labeled as 1).
 Our CNN model is based on 2,800 images that have been resized and normalized, the files formats is PNG‬, JPG‬. 
 The images are divided into a training set that contains 90% from data and a testing set that contains the remaining 10%.
 
 *CNN model architecture*

 Convolutional Layers: for feature extraction from images, applying 32 or 64 filters with a size of 3x3, the activation function used id ReLU .
 MaxPooling Layers: for reducing the spatial dimensions to a size of 2x2.
 Flatten: converts the multi-dimensional output of previous layers into a one-dimensional vector for input into fully connected layers.

 The model is trained using binary cross-entropy loss and the Adam optimizer. It is validated with 20% of the training data reserved for validation.
 The model employs 4-fold cross-validation to ensure robust performance.
 The following callbacks are used during training:
