Local Linear Learned Image Processing Pipeline

Automatically designing an image processing pipeline for a five-band camera prototype using the local, linear, learned (L3) method

The development of an image processing pipeline for each new camera design can be time-consuming. To speed camera development, we developed a method named L (Local, Linear, Learned) that automatically creates an image processing pipeline for any design. In this paper, we describe how we used the L method to design and implement an image processing pipeline for a prototype camera with five color...

Automating the design of image processing pipelines for novel color filter arrays: Local, Linear, Learned (L) method

The high density of pixels in modern color sensors provides an opportunity to experiment with new color filter array (CFA) designs. A significant bottleneck in evaluating new designs is the need to create demosaicking, denoising and color transform algorithms tuned for the CFA. To address this issue, we developed a method(local, linear, learned or L) for automatically creating an image processi...

Local Linear Approximation for Camera Image Processing Pipelines

Modern digital cameras include an image processing pipeline that converts raw sensor data to a rendered RGB image. Several key steps in the pipeline operate on spatially localized data (demosaicking, noise reduction, color conversion). We show how to derive a collection of local, adaptive linear filters (kernels) that can be applied to each pixel and its neighborhood; the adaptive linear calcul...

Runtime Assignment of Reconfigurable Hardware Components for Image Processing Pipelines

The combination of hardware acceleration and flexibility make FPGAs important to image processing applications. There is also a need for efficient, flexible hardware/software codesign environments that can balance the benefits and costs of using FPGAs. Image processing applications often consist of a pipeline of components where each component applies a different processing algorithm. Component...
