Detail Recovery for Single-image Defocus Blur
We presented an invited talk at the MIRU-IUW workshop on correcting photometric distortions in photographs. In this paper, we describe our work on addressing one form of this distortion, namely defocus blur. Defocus blur can lead to the loss of ne-scale scene detail, and we address the problem of recovering it. Our approach targets a single-image solution that capitalizes on redundant scene inf...
متن کاملBlind Single-Image Super Resolution Reconstruction with Defocus Blur
A blind single-image super resolution method is proposed to enhance the spatial resolution of the image with defocus blur. Firstly, according to the low resolution imaging model, a framework of blind singleimage super resolution reconstruction is presented. Secondly, utilizing Wiener filtering algorithm, the errorparameter curve of the defocus blurred image was generated, through which the defo...
متن کاملFace Recognition using Local Ternary Pattern for Low Resolution Image
Face Recognition system is one of an effective system which is used for the identification of a person from a video frame or a digital image. The concept of FRS is primarily used in the field of security systems and hence can be get compared to other systems which are biometric in nature such as IRIS Recognition or Fingerprint systems. Apart from these techniques, Local Binary Patterns (LBP) al...
متن کاملDefocus-based image segmentation
Foreground and background features are focused (or defocused) diierently in an image because corresponding objects are at diierent depths in the scene. This paper presents a novel approach for segmenting foreground and background in video images based on feature defocus. A modiied defocus measurement that distinguishes between high-contrast defocused edges and low-contrast focused edges is pres...
متن کاملAccelerating defocus blur magnification
A shallow depth-of-field is often used as a creative element in photographs. This, however, comes at the cost of expensive and heavy camera equipment, such as large sensor DSLR bodies and fast lenses. In contrast, cheap small-sensor cameras with fixed lenses usually exhibit a larger depth-of-field than desirable. In this case a computational solution is suggesting, since a shallow depth-of-fiel...
