At the core of a CNN, convolution filters (also called kernels) play a crucial role in detecting patterns within an image.Convolution filters slide over the image, performing element-wise multiplication and summation to extract features like edges, corners, and textures.Multiple filters are applied in each convolutional layer, mimicking the progressive understanding of an image from basic to complex elements.CNNs enable automatic learning of relevant patterns, eliminating the need for manual coding of feature detection.
