Abstract

Last Semester Evaluation is part of study result evaluation which use Computer Answer Sheet as
the place for student to write the answers. Computer Answer Sheet generally corrected by spesific
scanner with the expensive price, so some school choose to correct the answer sheet manually
like at Ar-Rahman Sumoyono Islamic Senior High School. To solve that problem, this research
is one of some solution which use the benefit of smartphone and digital image processing
technology specially canny edge detection method. This prototype will combinate canny edge
detection method to find the edge of image and hough circle transformation to detect marked
answers. This prototype use the convertible canny parameter value by user, consider the
brightness value of every captured image is different. Result of detected answer with hough circle
transformation will be tracked to determine the choosen answer. The choosen an swer by students
will be saved in array, and will be matched with the answer keys which saved in SQLite database.
The result of comparation between the result of detected answer with the real answer based on
30 answer sheet samples is 91,41 %.
Keywords: android, answer sheet, canny. .
