Resizing an image in MATLAB and its effect

Question

If I resize an image in MATLAB , what effect will that have on the original image. Say for instance I have an image of size 437x167 and I want to resize it to 256x256 . Will there be any details that will go missing from such operation?

Thanks.

if i understand you correctly you mean: "what are the results on an image after using matlab's built in function imresize ?" by looking at the documentation of imresize you can see that you can choose what algorithm you want to use through the parameters of imresize. the best answer can be found by googeling the respective algorithms and reading what is the data loss caused by each of these algorithms
