چکیده

We propose an algorithm to process images using their local information. Each image is tiled with overlapping neighborhoods. Then, each region is enhancement independently. The overlapping tiles are then seamlessly mosaicked to construct the multi-focus image. Our approach is presented for images from optical and fluorescent microscopy and demonstrates better local contrast preservation in comparison with traditional global approaches (histogram stretching or equalization).

Tile-based Framework for Local Enhancement of Bio Imagery

We present a simple framework for image enhancement using local image information. The main idea is to divide the image into small tiles and individually enhance each of these tiles. Enhanced tiles are then mosaicked back together. Our approach is presented for enhancement of fluorescent microscopy images and demonstrates better local contrast preservation and saturation reduction in comparison...

UWIT: Underwater Image Toolbox for Optical Image Processing and Mosaicking in MATLAB

This paper shows results from our development of an extended MATLAB image processing toolbox, which implements some useful optical image processing and mosaicking algorithms found in the literature. We surveyed and selected algorithms from the field which showed promise in application to the underwater environment. We then extended these algorithms to explicitly deal with the unique constraints...

Orthorectified Mosaicking of Images from Small-scale Unmanned Aerial Vehicles

Unmanned aerial vehicles (UAVs) have been recently deployed in various civilian applications such as environmental monitoring, aerial imagery, and surveillance. Small-scale UAVs are of special interest for first responders since they can rather easily provide bird’s eye view images of disaster areas. For such UAVs the number of images and the positions where to capture them are predefined due t...

Mosaicking of Unmanned Aerial Vehicle Imagery in the Absence of Camera Poses

The mosaicking of Unmanned Aerial Vehicle (UAV) imagery usually requires information from additional sensors, such as Global Position System (GPS) and Inertial Measurement Unit (IMU), to facilitate direct orientation, or 3D reconstruction approaches (e.g., structure-from-motion) to recover the camera poses. In this paper, we propose a novel mosaicking method for UAV imagery in which neither dir...

A General Framework for 1-D Histogram-baesd Image Contrast Enhancement

In this paper, a general framework for image contrast enhancement algorithm based on an optimization problem is presented. Through this optimization, the intensities can be better distributed. The algorithm is based on the facts that the histogram of the enhanced image is close to the input image histogram and uniform distribution, simultaneously. Based on this fact, we obtain a closed form opt...
