+
+# Inpainting is the process of constructing lost or deteriorated parts of an
+# image or video. It is also used for removing undesired elements from a scene.
+#  
+# The basic idea of inpainting is: Replace those bad marks (or undesired elements) with its 
+# neighbouring pixels so that it looks like the neighbourhood.
+
+# In this demo we will be removing an undesired element form an image.

+# pixels where mask is set to true will be inpainted
+mask[50:350,300:400] .= true;
+Gray.(mask)

+# inpaint take the parametes image, mask and algorithm.
