Perhaps you should try some spelling variations:
"and computation using java programming" » "and computations using java programming" (Expand search), "and computation in java programming" (Expand search), "and composition using java programming" (Expand search), "and computation using and programming" (Expand search), "and computation using based programming" (Expand search), "and computation using goal programming" (Expand search), "and computational using java programming" (Expand search), "of computation using java programming" (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: "((\"and computation using java programming\") OR (\"using opencv python python programming\"))~".
• Removing quotes may allow a broader search: (( and computation using java programming ) OR ( using opencv python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("and computation using java programming") OR ("using opencv python python programming"))*.
