I have a 3D matrix, how to do clustering of this matrix?

The size of my matrix is 176*256*256. Should I save this file in .bmp and carry out clustering or convert it in 2D matrix then carry out clustering? If yes then please help me by sharing your thoughts as to how can I do it either way?

Whether dimention affects clustering results, I think no, assigns different clusters values to the categories. You may apply the cluster in lower dimension (K-means), get the cluster range and assign the same to the original data.

Do you know in advance how many clusters there should be? If so, you can use kmeans().
