Digital watermark technology hides copyright information in digital images, effectively protecting the of images. At present, color image watermarking algorithm still has defects such as inability to balance robustness, invisibility and weak anti-attack ability. Aiming at above problems, this paper studies method based on discrete wavelet transform cosine transform. Then proposes a blind QR cod...

System development uses waterfall method.Findings/result: Based results tests that have been carried out, resulting is 87.5% with varying light intensities 92.3% using a intensity 5362 Lux.Original...

Image hashing is a new technology in multimedia security. It maps visually identical images to the same or similar short strings called image hashes, and finds applications in image retrieval, image authentication, digital watermarking, image indexing, and image copy detection. This paper presents a perceptual hashing for color images. The input image in RGB color space is firstly converted int...

This paper proposes a novel idea of combining the color spaces as a pair in getting the improved results in the human skin detection. Skin detection methods that can be used in various applications of image segmentation are evaluated. The performance of the three pixel based classification algorithms are analyzed. The color images of human faces are segmented into skin regions on the basis of p...

In recent years, generative adversarial networks (GANs) have been widely used to generate realistic fake face images, which can easily deceive human beings. To detect these some methods proposed. However, their detection performance will be degraded greatly when the testing samples are post-processed. this paper, experimental studies on detecting post-processed GAN-generated images find that (a...

Gray scale image colorization is a useful application in the world of image processing. This work presents a general technique for “colorizing” grayscale images by transferring color between a source or color image and a destination or target or grayscale image by matching luminance and texture information between the images. This technique of the gray image coloring uses a very simple algorith...

A novel single-channel color image encryption algorithm is proposed, which utilizes the reality-preserving fractional discrete cosine transform in YCbCr space. The color image to be encrypted is decomposed into Y, Cb, and Cr components, which are then separately transformed by Discrete Cosine Transform (DCT). The resulting three spectra sequences, obtained by zig-zag scanning the spectra matric...

This paper presents a reliable method for detecting human faces in color images. The system is based on the visual information of the face and is commenced with the detection of face regions by connected component analysis of the skin color segmentation of images in HSV,YCBCR,YIQ color model and the Fuzzy membership function. The Fuzzy Membership function is applied to search for possible face ...

Batik is a sort of cultural heritage fabric that originated in many areas Indonesia. It can be traced back to different parts Each region, particularly Semarang Central Java, Indonesia, has its design. Unfortunately, due lack knowledge, not all residents recognize the types batik. Therefore, this study proposed an automated method for classifying batik was classified into five categories accord...

Ancillary structures are essential for highways’ safe operationality but mainly prone to environmental corrosion. The traditional way of inspecting ancillary is manned inspection, which laborious, time-consuming, and unsafe inspectors. In this paper, a novel image processing technique was developed autonomous corrosion detection in-service structures. authors successfully leveraged features in ...
