  - getHistogram
```
public int[] getHistogram()
```
    Description copied from class: ImageProcessor
    
    Returns the histogram of the image or ROI. Returns a luminosity histogram for RGB images and null for float images.
    For 8-bit and 16-bit images, returns an array with one entry for each possible value that a pixel can have, from 0 to 255 (8-bit image) or 0-65535 (16-bit image). Thus, the array size is 256 or 65536, and the bin width in uncalibrated units is 1.
    For RGB images, the brightness is evaluated using the color weights (which would result in a float value) and rounded to an int. This gives 256 bins. FloatProcessor.getHistogram is not implemented (returns null).
    
    Specified by:
    
    getHistogram in class ImageProcessor
  - getHistogram
```
public int[] getHistogram(ImageProcessor mask)
```
  - threshold
```
public void threshold(int level)
```

```
public FloatProcessor toFloat(int channelNumber,
                              FloatProcessor fp)
```
    Returns a FloatProcessor with the same image, no scaling or calibration (pixel values 0 to 255). The roi, mask, lut (ColorModel), threshold, min&max are also set for the FloatProcessor
    
    Specified by:
    
    toFloat in class ImageProcessor
    
    Parameters:
    
    channelNumber - Ignored (needed for compatibility with ColorProcessor.toFloat)
    
    fp - Here a FloatProcessor can be supplied, or null. The FloatProcessor is overwritten by this method (re-using its pixels array improves performance).
    
    Returns:
    
    A FloatProcessor with the converted image data
  - setPixels
```
public void setPixels(int channelNumber,
                      FloatProcessor fp)
```
    Sets the pixels from a FloatProcessor, no scaling. Also the min&max values are taken from the FloatProcessor.
    
    Specified by:
    
    setPixels in class ImageProcessor
    
    Parameters:
    
    channelNumber - Ignored (needed for compatibility with ColorProcessor.toFloat)
    
    fp - The FloatProcessor where the image data are read from.
  - isBinary
```
public boolean isBinary()
```
    Returns 'true' if this is a binary image (8-bit-image with only 0 and 255).
    
    Overrides:
    
    isBinary in class ImageProcessor
  - getBitDepth
```
public int getBitDepth()
```
    Description copied from class: ImageProcessor
    
    Returns the bit depth, 8, 16, 24 (RGB) or 32. RGB images actually use 32 bits per pixel.
    
    Overrides:
    
    getBitDepth in class ImageProcessor
  - createMask
```
public ByteProcessor createMask()
```
    Returns a binary mask, or null if a threshold is not set.
    
    Overrides:
    
    createMask in class ImageProcessor
