The storage of colour information in a greyscale image is not a new idea. Various techniques have been proposed using different colour spaces including the standard RGB colour space, the YUV colour space, and the YCbCr colour space. This paper extends the results described in [1] and [2]. While [1] describes the storage of colour information in a greyscale image using Haar wavelets, and [2] add...

Over the last few years, skin segmentation has been widely applied in diverse aspects of computer vision and biometric applications including face detection, tracking, face/hand-gesture recognition systems. Due to its importance, we observed a reawakened interest developing approaches. In this paper, offer comparison between five major supervised learning algorithms for segmentation. The involv...

Color models are widely used in image recognition because they represent significant information. On the other hand, texture analysis techniques have been extensively used for facial feature extraction. In this paper; we extract discriminative features related to facial attributes by utilizing different color models and texture analysis techniques. Specifically, we propose novel methods for tex...

Real time faces detection and face tracking is one of the challenging problems in application like computer human interaction, video surveillance, biometrics etc. In this paper we are presenting an algorithm for real time face detection and tracking using skin color segmentation and region properties. First segmentation of skin regions from an image is done by using different color models. Skin...

Timely harvest can effectively guarantee the yield and quality of rapeseed. In order to change artificial experience model in monitoring rapeseed period, an intelligent prediction method period based on deep learning network was proposed. Three varieties field were divided into 15 plots, mobile phones used capture images silique stalk manually measure yield. The daily three grades more than 90%...

This paper describes the use of some color spaces in JPEG image compression algorithm and their impact terms quality ratio, then proposes adaptive space models (ACSM) to improve performance lossy algorithm. The proposed ACSM consists of, dominant analysis YCoCg family. family is composed three spaces, which are YCcCr, YCpCg YCyCb. colors developed enables automatically select one based on suita...

In this paper, we propose a effective fog-free methodology for remove fog from input image.In our method, firstly, the original image is converted from RGB to YCbCr. Secondly, compute the intensity component of the YCbCr image and key observation of the all pixels of the image. Most local patches in fog-free outdoor images contain some pixels which have very low intensities in at least one colo...

Information hiding of data in an image file is needed by its owner to set his ownership in a logo as a watermark embedded in the image file. Hiding the logo in the image was done in several methods. One of the methods is domain transform using 2D-DCT in which data is embedded in frequency domain of the image. First, the host RGB image is converted to certain color space. The available and chose...

Illumination correction or Color Constancy (CC) is the ability of humans for resolving the apparent colors of objects in a given scene independently of the illumination source. For robust skin detection in images/videos, we evaluate and investigate the effect of CC approaches on static skin segmentation approaches. The effect of five CC approaches namely Gray-Edge CC, Gray-World CC, max-RGB CC,...

The paper presents an innovative technique for colorization of grayscale images. Here the colors from some source color image are picked up and sprayed into the to be colored grayscale image. The color palette used in colorization technique discussed here is generated using the Linde Buzo and Gray (LBG) codebook. The technique is tested using various VQ codebook sizes like 32, 64, 128, 256 and ...
