What does Img_as_float do?

They do different things: img_as_float converts an image from any type to a floating point type in [0, 1], whether it is a color image or not. For example, a (512, 512) image containing uint8 values in the range 0-255 will be converted to a (512, 512) image containing float64 values in the range 0-1.

How to convert image to float in Python?

You might have to do img = img. astype(float)/255 if you want to convert integer values from 0 to 255 to a float in the range 0 to 1.

Can pixel values be float?

instead of integer stored pixel values, float stored pixel values are used. Bits Stored (0028,0101) and High Bit (0028,0102) are not used because the stored pixel values always occupy the entire word. Pixel Representation (0028,0103) is not used because the stored pixel values are always signed.
