Curves to image convert7/14/2023 The SLIM Curve library code is written in C89 compatible C and is thread-safe for fitting multiple pixels concurrently. This works with single, double and triple exponential models, as well as stretched exponential. The second is a Levenberg-Marquardt algorithm or LMA that uses an iterative, least-squares-minimization approach to generate a fit.The first is a triple integral method that does a very fast estimate of a single exponential lifetime component.There are two algorithms used for curve fitting within SLIM Curve: SLIM Curve was used for FLIM functionality in the Advanced Technology Group’s Time Resolved Imaging (TRI2) software, as well as in the SLIM Curve plugin for ImageJ. It was developed by Paul Barber and the Advanced Technology Group at the Cancer Research UK and Medical Research Council Oxford Institute for Radiation Oncology, as well as the Laboratory for Optical and Computational Instrumentation at the University of Wisconsin-Madison. SLIM Curve is an exponential curve fitting library used for Fluorescent Lifetime Imaging (FLIM) and Spectral Lifetime Imaging (SLIM). The image should start rendering or the video should start playing at a slow rate.The SLIM Curve plugin for ImageJ has been discontinued in favor of FLIMJ. Load index.html into a web browser and put f=1 into the first formula in the formula window. Should eventually show that the server is running on localhost:5000. Run backend (This may take a while depending on the size and complexity of the frames). These only really matter if you are rendering a video. You can change the DYNAMIC_BLOCK, BLOCK_SIZE, and MAX_EXPR_PER_BLOCK to change the number of expressions the backend will send to the frontend per call (too much will cause a memory error, too little could kill the backend with too many requests). Show the grid in the background while rendering Works best in Firefox, as chromium browsers will constantly prompt for downloadsĬreates less edges but is still accurate (leads to faster renders) If true, each frame is screenshotted automatically. The folder where the frames are stored relative to this fileĭownload each rendered frame automatically (works best in Firefox) Maximum lines per block, doesn't affect lines per frame Note that a "block" refers to what is passed from the backend to the frontend per HTTP request. mkdir framesĬonstants in the backend.py file can be changed to optimise or customise your render. Works best with 360p to 480p resolution (may have to lower the resolution further with more complex frames). To render just a single image, add a single image named frame1.png in the directory. You can find it produces under the \\wsl$\Ubuntu-20.04\home path on your PC.Īpt install git python3-dev python3-pip build-essential libagg-dev libpotrace-dev pkg-configĬreate a directory called frames and add images named frame%d.png where %d represents the frame-number starting from 1. The easiest way to do this on Windows is to download WSL to run all the commands below. Setup This guide won't work out of the box on Windows.
