A Specular Highlight Removal Method with Shape Constrained Inpainting
نویسندگان
چکیده
The existence of specular highlight is a great obstacle of shape recovery. For a single gray-scale image with only intensity information, the existed highlight detection methods based on chroma or polarization analysis cannot directly be applied on it. So, a method using surface shape is provided, it makes full use of the imaging process. Through the surface normal estimation, compute the maximum a posteriori probability of each reflection composition under simulated annealing and detect the highlight areas. Finally, remove the highlight based on the assumption of curvature continuity. Experiments reveal that this method is effective on synthetic and real-world images, improves the accuracy of specular highlight removed for image combined specular highlight.

Highlight Removal by Illumination-Constrained Inpainting
We present a single-image highlight removal method that incorporates illumination-based constraints into image inpainting. Unlike occluded image regions filled by traditional inpainting, highlight pixels contain some useful information for guiding the inpainting process. Constraints provided by observed pixel colors, highlight color analysis and illumination color uniformity are employed in our...
متن کاملVariational Specular Separation Using Color and Polarization
In this paper, we propose a method that separates specular reflections from polarized color images. With line constraints in RGB color space and spatial domain information, we used a Variational energy minimization approach to restore diffuse reflections. With anisotropic smoothing, our method preserves the shape of textures and successfully separates specular reflections. Also, saturation of s...
متن کاملAdaptive specular reflection detection and inpainting in colonoscopy video frames
Colonoscopy video frames might be contaminated by bright spots with unsaturated values known as specular reflection. Detection and removal of such reflections could enhance the quality of colonoscopy images and facilitate diagnosis procedure. In this paper we propose a novel two-phase method for this purpose, consisting of detection and removal phases. In the detection phase, we employ both HSV...
متن کاملQuality Improvement of Endoscopy Videos
We address two quality issues in endoscopy videos originating from: (a) Colour Channel Misalignment: In current endoscope systems, the colour channel images are most commonly acquired sequentially at different time instances. Whenever the camera moves significantly between acquisition instances, the colour channels get misaligned. This misalignment degrades the quality of the video due to the a...
متن کاملMaking Shape from Shading Work for Real-World Images
Although shape from shading (SfS) has been studied for almost four decades, the performance of most methods applied to realworld images is still unsatisfactory: This is often caused by oversimplified reflectance and projection models as well as by ignoring light attenuation and nonconstant albedo behavior. We address this problem by proposing a novel approach that combines three powerful concep...
