The user interface in OpenCV has a Trackbar. This is a really useful feature for interacting with images. By adjusting the slider the user can manipulate the image allowing for the adjustment of threshold values until the image display is optimised. When I wrote about interactive image segmentation I noted one of the critical things… Read More »Interactive Trackbar to edge detect Sentinel 2 data
I have been working with OpenCV for a while now and I still find the speed of results very impressive. It makes for a compelling case for its use in image processing. Computer Vision, at least to me, represents such an incredible opportunity for Remote Sensing specialists as well as non-specialists. I have been meaning… Read More »Beginners guide to user Interaction with OpenCV in Python
This week I have been thinking about image stretching. I want to start with a quote taken from the concluding remarks of Image Processing and GIS for Remote Sensing. Image Processing can never increase the information provided in the original image data, but the use of appropriate image processing can improve visualisation, comprehension and analysis… Read More »Contrast Limited Adaptive Histogram Equalization (CLAHE) with Sentinel 2a
By 2030 the UK would like to have a £40 billion or 10% slice of the global space economy. In 2015 the market was estimated at £13.7 billion. Ambitious targets? At the UK Space Conference this week I heard a speaker who noted that the Space economy was second in size only to Oil and… Read More »UK Space Conference 2017
