Abstract
An output apparatus determines pixels that form an area equal to or greater than a predetermined size and whose pixel values are not different from pixel values of neighboring pixels, and pixels that form an area not equal to or greater than the predetermined size. The apparatus reduces the pixel values of the determined pixels and outputs a binary image formed by the determined pixels with the reduced pixel values.
Claims7
A non-transitory computer readable storage medium having stored therein an output program causing a computer serving as an information processing apparatus to execute a process comprising:
- calculating, for each of pixels that form a binary image, a first value by summing a pixel value of a pixel
- of interest and pixel values of a predetermined number of pixels neighboring the pixel of interest;
- calculating, for each of the pixels that form the binary image, a second value by calculating difference values each between the calculated first value of the pixel of interest and the calculated first value of each of the neighboring pixels and summing absolute values of the difference values;
- determining pixel whose second value that is smaller than a predetermined value;
- changing the pixel values of the determined pixels from “1” to “0”;
- and
- outputting the binary image with the changed pixel values.
An information processing apparatus, comprising:
- a calculating unit that calculates, for each of pixels that form a binary image, a first value by summing a pixel value of a pixel of interest and pixel values of a predetermined number of pixels neighboring the pixel of interest;
- a calculating unit that calculates, for each of the pixels that form the binary image, a second value by calculating difference values each between the calculated first value of the pixel of interest and the calculated first value of each of the neighboring pixels and summing absolute values of the difference values;
- a determining unit that determines pixel whose second value that is smaller than a predetermined value;
- a changing unit changes the pixel values of the determined pixels from “1” to “0”;
- and
- an output unit that outputs the binary image with the changed pixel values.
An output method comprising:
- receiving a binary image to be output;
- calculating, for each of pixels that form the received binary image, a first value by summing a pixel value of a pixel
- of interest and pixel values of a predetermined number of pixels neighboring the pixel of interest;
- calculating, for each of the pixels that form the binary image, a second value by calculating difference values each between the calculated first value of the pixel of interest and the calculated first value of each of the neighboring pixels and summing absolute values of the difference values;
- determining pixel whose second value that is smaller than a predetermined value;
- changing the pixel values of the determined pixels from “1” to “0”;
- and
- outputting the binary image with the changed pixel values to a user terminal.
