Convolutional Neural Networks (CNNs) process images efficiently by using convolutional layers to learn features directly from the input images. This method involves applying filters (kernels) that convolve across the image to detect various patterns such as edges, textures, and shapes at different spatial hierarchies. Each convolutional layer helps extract increasingly complex features from the image, which are essential for tasks like image classification, object detection, and segmentation.

The architecture of CNNs typically includes additional layers such as pooling layers that reduce the spatial dimensions of the feature maps, allowing the network to focus on the most important features while minimizing computation. The hierarchical learning of features enables CNNs to generalize well to new images, making them highly effective in computer vision applications.

In contrast, the other options do not accurately reflect the processing mechanism of CNNs. Decision trees are a different type of model used for classification and regression tasks, while flattening images loses spatial information and is usually a step taken before feeding data into fully connected layers, not a processing method by itself. Linear regression models apply to continuous output predictions and do not capture the complex spatial relationships found in image data.
