+    Nearest neighbor interpolation is to perform nearest neighbor interpolation
+    in both the 3rd dimention(in height direction) and the 4th dimention(in width 
+    direction) on input tensor.
+            
+    Bilinear interpolation is an extension of linear interpolation for 
+    interpolating functions of two variables (e.g. H-direction and 
+    W-direction in this op) on a rectilinear 2D grid. The key idea is 
+    to perform linear interpolation first in one direction, and then 
+    again in the other direction.
+
+    Align_corners and align_mode are optinal parameters,the calculation method 
+    of interpolation can be selected by them.
+
+    Example:
+
+      For scale:
+      
+        if align_corners = True && out_size > 1 :
+
+          scale_factor = (in_size-1.0)/(out_size-1.0)
