Corresponding source code
After some test in which very simple operation (subtraction of images) were done, the results were that considering `int32' data type was more time consumption than using `float32'.
For example:
finished in 0.111564. While
finished in 0.120998.
Note that images are different names but the size is the same.
That difference in time makes no sense and this overhead along big projects will cause a lot of extra time in processing data.
