Abstract:
The purpose of this thesis is to develop a program that can distinguish and specify whether digital images loaded into the program are nude. The program is used to detect inappropriate images in any media especially on internet websites. The pixel properties of the images such as YCbCr range, eccentricity, orientation are examined. The images are converted from RGB model into YCbCr model.
Then each pixel is compared to YCbCr range: Y > 100, 100 < Cb< 120 or 128 < Cb < 130 and 130 < Cr< 160. The images which have the number of pixel in the mentioned range compared with total pixels of the image greater than 0.4 and the eccentricity, orientation in the database range are classified and specified to be nude images.
