+	 * {@link RealType} source {@link RandomAccessible}, using a list of
+	 * {@link Shape}s as a structuring element, and writes the result on a
+	 * specified target which must be an {@link IterableInterval}.
+	 *
+	 * See <a href="http://en.wikipedia.org/wiki/Top-hat_transform"> Top-hat
+	 * transform</a>.
+	 * <p>
+	 * <b>Careful: Target must point to a different structure than source.</b>
+	 * In place operation will not work but will not generate an error.
+	 * <p>
+	 * It is the caller responsibility to ensure that the source is sufficiently
+	 * padded to properly cover the target range plus the shape size. See
+	 * <i>e.g.</i> {@link Views#extendValue(RandomAccessibleInterval, Type)}
+	 * <p>
+	 * It is limited to flat structuring elements, only having
+	 * {@code on/off} pixels, contrary to grayscale structuring elements.
+	 * This allows to simply use a {@link Shape} as a type for these structuring
+	 * elements.
+	 * <p>
+	 * The structuring element is specified through a list of {@link Shape}s, to
+	 * allow for performance optimization through structuring element
+	 * decomposition. Each shape is processed in order as given in the list. If
+	 * the list is empty, the target receives a copy of the source.
+	 * <p>
+	 * This method differs from
+	 * {@link #blackTopHat(RandomAccessible, IterableInterval, List, int)}
+	 * only in that its parameter order is tailored to an Op. The output comes
+	 * last, and the primary input (the input image) comes first.
