Bokeh Effect in Images on Objects Based on User Interest
2019 IEEE International Conference on Electronics, Computing and Communication Technologies (CONECCT)
Year: 2019 | Conference Paper |
Humans pay visual attention to those objects in the visual field that they are most interested in seeing. The Bokeh effect is a popular blurring effect in photography, where the object of interest is emphasized by blurring other objects. In this paper, we apply the principle of visual attention to the user's object of interest to post processing of photos taken using a smartphone. We simulate the ...Show More

This paper reviews the first AIM challenge on bokeh effect synthesis with the focus on proposed solutions and results. The participating teams were solving a real-world image-to-image mapping problem, where the goal was to map standard narrow-aperture photos to the same photos captured with a shallow depth-of-field by the Canon 70D DSLR camera. In this task, the participants had to restore bokeh e...Show More

GBSD: Generative Bokeh with Stage Diffusion
ICASSP 2024 - 2024 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP)
Year: 2024 | Conference Paper |
The bokeh effect is an artistic technique that blurs out-of-focus areas in a photograph and has gained interest due to recent developments in text-to-image synthesis and the ubiquity of smartphone cameras and photo sharing apps. Prior work on rendering bokeh effects have focused on manipulating photographs using classical computer graphics or neural rendering techniques, but have either depth disc...Show More
BokehMe++: Harmonious Fusion of Classical and Neural Rendering for Versatile Bokeh Creation
Juewen Peng;Zhiguo Cao;Xianrui Luo;Ke Xian;Wenfeng Tang;Jianming Zhang;Guosheng Lin
Despite significant advancements in simulating the bokeh effect of Digital Single Lens Reflex Camera (DSLR) from an all-in-focus image, challenges remain in processing highlight points, preserving boundary details for in-focus objects and processing high-resolution images efficiently. To tackle these issues, we first develop a ray-tracing-based bokeh simulator. An innovative pipeline with weight r...Show More
Efficient Bokeh Effect Rendering using Generative Adversarial Network
2020 IEEE International Conference on Consumer Electronics - Asia (ICCE-Asia)
Year: 2020 | Conference Paper |
Cited by: Papers (2)
The bokeh effect in photography is an artistic effect that makes the subject stand out by intentionally distorting the focus of the background while focusing on the subject. In this paper, we propose an end-to-end deep learning model that generates bokeh images from wild HD images. The proposed generative adversarial network model consists of a generator and a double-scale discriminator. It is so ...Show More
Circle Fitting to Overcome Vignetting Effect of Afocal Tracking System
2014 International Symposium on Optomechatronic Technologies
Year: 2014 | Conference Paper |
Cited by: Papers (1)
A focal tracking system is a tracing system that tracks a special marker called a focal marker. The cameras of a focal tracking system obtain images including bokeh which is shown from the a focal marker. Finding accurate center of bokeh is important for high precision position tracking of a focal marker. However, a focal tracking system suffers from vignetting effect which makes it difficult to f...Show More
A Bokeh Image Generation Technique using Machine Learning
2022 Tenth International Symposium on Computing and Networking (CANDAR)
Year: 2022 | Conference Paper |
In photography, bokeh is the aesthetic effect appearing in out-of-focus areas. Bokeh is often used to emphasize a subject or to express a beautiful background. However, such bokeh effects can be expressed with cameras equipped with large-aperture lenses but are not easy to realize with small-aperture lenses. The main contribution of this paper is to propose a technique to generate a bokeh image fr...Show More
Depth-Guided Dense Dynamic Filtering Network for Bokeh Effect Rendering
Kuldeep Purohit;Maitreya Suin;Praveen Kandula;Rajagopalan Ambasamudram
2019 IEEE/CVF International Conference on Computer Vision Workshop (ICCVW)
Year: 2019 | Conference Paper |
Cited by: Papers (23)
Bokeh effect refers to the soft defocus blur of the background, which can be achieved with different aperture and shutter settings in a camera. In this work, we present a learning-based method for rendering such synthetic depth-of-field effect on input bokeh-free images acquired using ordinary monocular cameras. The proposed network is composed of an efficient densely connected encoder-decoder bac...Show More
A Fixed-Scale Pixelated MIMO Visible Light Communication System
A pixelated MIMO wireless optical communication system is introduced, which transmits a series of time-varying coded images that can be received and decoded by commercial digital cameras. The system exploits the bokeh effect to obtain fixed-scale images at all link distances by placing a convex lens in front of the transmitter array at its focal length and focusing the receiver at infinity. This s...Show More
Depth Aware Portrait Segmentation Using Dual Focus Images
2018 IEEE International Conference on Multimedia and Expo (ICME)
Year: 2018 | Conference Paper |
Cited by: Papers (1)
The rapid development of camera in hand-held devices and the emergence of social media has led to an uprise in capturing self-portrait images. Augmenting these images for beautification or applying special effects to mimic DSLR camera has become a popular practice. Most of these effects require separation of foreground from background where the effect can be applied solely on background. To employ...Show More
Constrained Predictive Filters for Single Image Bokeh Rendering
Bolun Zheng;Quan Chen;Shanxin Yuan;Xiaofei Zhou;Hua Zhang;Jiyong Zhang;Chenggang Yan;Gregory Slabaugh
Bokeh rendering is a technique used to take pictures with out-of-focus areas to highlight regions of interest. Due to limitations in hardware and shooting condition, rendering a bokeh image from a full-focus image has attracted a lot of interest. In this paper, we model bokeh rendering as the combination of salient region retention and bokeh blurring, and propose a neural network to generate a rea...Show More
