Perhaps you should try some spelling variations:
"based computational model computer program" » "and computational model computer program" (Expand search), "by computational model computer program" (Expand search), "based computational modeling computer program" (Expand search), "based computational vhdl computer program" (Expand search)
"using coding opencv python programming" » "using using opencv python programming" (Expand search), "using codigo opencl python programming" (Expand search), "using coding pnc python programming" (Expand search), "using coping opencv python programming" (Expand search), "using coating opencv python programming" (Expand search), "using cooking opencv python programming" (Expand search)

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("based computational model computer program") OR ("using coding opencv python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"based computational model computer program\") OR (\"using coding opencv python programming\"))".
• Removing quotes may allow a broader search: (( based computational model computer program ) OR ( using coding opencv python programming )).
• Adding a wildcard symbol may retrieve word variants: (("based computational model computer program") OR ("using coding opencv python programming"))*.
