How to measure the similarity between two images?
I have two group images for cat and dog. And each group contain 2000 images for cat and dog respectively.
My goal is try to cluster the images by using k-means.
Assume image1 is x, and image2 is y.Here we need to measure the similarity between any…

How can I plot/display a dataset or an image distribution?
I want to view a specific image or a dataset's distribution, and see if they are different.
Does simply writing something like :
# mydataset.shape = (50k,32,32,3)
plt.hist(mydataset.reshape(-1))
do the trick? or should I be doing something…

DBScan for image segmentation and clustering: how does it work?
I think I have understood the DBScan algorithm for 2D data points. We can consider the example in scikit-learn. They generate a set of data points:
from sklearn.datasets import make_blobs
from sklearn.preprocessing import StandardScaler
centers =…

Image Super-resolution Connecting Subimages
I'm working with image super-resolution on terrain height data. Currently, I'm cutting the input data into smaller pieces (20 x 20 rather than 10800 x 10800).
After the upscale 20x20 -> 40x40, piecing the resulting images together causes artifacts…
