The authors make the assumption that the image is acquired using a color filter array, and that tampering removes the artifacts due to a demosaicing algorithm. This article extracts the image features based on the variance of the prediction error and create image feature likelihood map to detect and locate the image tampered areas. The experimental results show that the proposed method can detect and locate the splicing tampering areas precisely. Compared with bi-linear interpolation, this method can reduce the prediction error and improve the detection accuracy.<\/p>","DOI":"10.4018\/ijdcf.2019040101","type":"journal-article","created":{"date-parts":[[2019,2,22]],"date-time":"2019-02-22T15:12:45Z","timestamp":1550848365000},"page":"1-12","source":"Crossref","is-referenced-by-count":2,"title":["Digital Image Forensics Based on CFA Interpolation Feature and Gaussian Mixture Model"],"prefix":"10.4018","volume":"11","author":[{"given":"Xinyi","family":"Wang","sequence":"first","affiliation":[{"name":"Beijing University of Posts and Telecommunications, Beijing, China"}]},{"given":"Shaozhang","family":"Niu","sequence":"additional","affiliation":[{"name":"Beijing University of Posts and Telecommunications, Beijing, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8910-2382","authenticated-orcid":true,"given":"Jiwei","family":"Zhang","sequence":"additional","affiliation":[{"name":"Beijing University of Posts and Telecommunications, Beijing, China"}]}],"member":"2432","reference":[{"key":"IJDCF.2019040101-0","doi-asserted-by":"publisher","DOI":"10.1016\/j.image.2013.03.006"},{"journal-title":"Color imaging array","year":"1976","author":"B.
