Webb24 juni 2024 · 3. Flatten and store all the image weights in a list. 4. Feed the above-built list to k-means and form clusters. Putting the above algorithm in simple words we are just extracting weights for each image from a transfer learning model and with these weights as input to the k-means algorithm we are classifying the image. Webb30 mars 2024 · After running the K-means clustering algorithm, we retrieve the cluster labels using the labels_ member array of the KMeans object. We reshape this back into the image’s original 2D shape on lines 68-69..
