Perhaps you should try some spelling variations:
"based computation in computer program" » "based computational in computer program" (Expand search), "based competition in computer program" (Expand search), "based compilation in computer program" (Expand search), "based computation and computer program" (Expand search), "based computation of computer program" (Expand search), "based imputation in computer program" (Expand search), "based computation _ computer program" (Expand search)
"using opencv python python programming" » "using opencv pythons python programming" (Expand search), "using opencv piton python programming" (Expand search), "using opencv pitons python programming" (Expand search), "using opencl python python programming" (Expand search), "using open python python programming" (Expand search), "usando opencv python python programming" (Expand search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"based computation in computer program\") OR (\"using opencv python python programming\"))~".
• Removing quotes may allow a broader search: (( based computation in computer program ) OR ( using opencv python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("based computation in computer program") OR ("using opencv python python programming"))*.
