- Abstract: Wide dynamic range (WDR) image tone mapping is in high demand in many
applications like film production, security monitoring, and photography. It is
especially crucial for mobile devices because most of the images taken today
are from mobile phones, hence such technology is highly demanded in the
consumer market of mobile devices and is essential for a good customer
experience. However, high-quality and high-performance WDR image tone mapping
implementations are rarely found in the mobile-end. In this paper, we introduce
a high performance, mobile-end WDR image tone mapping implementation. It
leverages the tone mapping results of multiple receptive fields and calculates
a suitable value for each pixel. The utilization of integral image and integral
histogram significantly reduce the required computation. Moreover, GPU parallel
computation is used to increase the processing speed. The experimental results
indicate that our implementation can process a high-resolution WDR image within
a second on mobile devices and produce appealing image quality.

We propose Image-GS, a content-adaptive image representation.
Using anisotropic 2D Gaussians as the basis, Image-GS shows high memory efficiency, supports fast random access, and offers a natural level of detail stack.
General efficiency and fidelity of Image-GS are validated against several recent neural image representations and industry-standard texture compressors.

Traditional image signal processing (ISP) pipeline in a smartphone camera consists of several image processing steps performed sequentially to reconstruct a high quality sRGB image from the raw sensor data.
Deep learning methods using convolutional neural networks (CNN) have become popular in solving many image-related tasks such as image denoising, contrast enhancement, super resolution, deblurring, etc.
In this paper we propose DelNet - a single end-to-end deep learning model - to learn the entire ISP pipeline within reasonable complexity for smartphone deployment.
