Detection of selected cells in Multi Choice Sheets

Abstract

In this paper we introduce a method based on vertical and horizontal histogram threshold to overcome the problem of detection the huge number of multichoice questioner sheets, where the manipulating, checking, find duplicate answer, and produce the result manually take a lot of time from human and also errors may be occur.The proposed algorithm work into two main steps first detect the grid found in each sheet by applying vertical and horizontal histogram, then detect the selected cell by also applying vertical and horizontal histogram depend on threshold value.The values of sheets stored in a data base to process it and the results printed either in word or excel form.We test this work on the evaluation supervisor questioners sheet for 50 students.
