Avidan 2007 computes all seams by removing each seam iteratively and storing an "index map" to record all the seams generated. However, the problem of making multiple seams at the same time is harder for two reasons: the energy needs to be regenerated for each removal for correctness and simply tracing back multiple seams can form overlaps. The calculation of the DP array can also be parallelized with some interprocess communication. The energy calculation is trivially parallelized for simple functions. The value in black represents the cumulative sum of energies leading up to and including that pixel.įor the lowest energies we have at the end, work back up the minimals to recover the seam with minimal energy. Each square represents a pixel, with the top-left value in red representing the energy value of that said pixel. The images below depict a DP process to compute one optimal seam.

If attempting to compute a vertical seam (path) of lowest energy, for each pixel in a row we compute the energy of the current pixel plus the energy of one of the three possible pixels above it.
Dynamic programming can be used to compute seams. Dynamic programming ĭynamic programming is a programming method that stores the results of sub-calculations in order to simplify calculating a more complex result. This can be done via Dijkstra's algorithm, dynamic programming, greedy algorithm or graph cuts among others. Computing seams Ĭomputing a seam consists of finding a path of minimum energy cost from one end of the image to another. It is also possible to invert step 4 so the algorithm enlarges in one dimension by copying a low energy seam and averaging its pixels with its neighbors. The seams to remove depends only on the dimension (height or width) one wants to shrink. Image Retargeting was invented by Vidya Setlur, Saeko Takage, Ramesh Raskar, Michael Gleicher and Bruce Gooch in 2005. The purpose of the algorithm is image retargeting, which is the problem of displaying images without distortion on media of various sizes (cell phones, projection screens) using document standards, like HTML, that already support dynamic changes in page layout and text but not images. Seam carving also allows manually defining areas in which pixels may not be modified, and features the ability to remove whole objects from photographs. It functions by establishing a number of seams (paths of least importance) in an image and automatically removes seams to reduce image size or inserts seams to extend it. Red could denote critically important folders, orange could indicate close deadline files, green - for those documents that can wait and so on.Ĭombination of color marks and assigned icons easily puts your folders in order allowing for more efficient and productive work.Seam carving (or liquid rescaling) is an algorithm for content-aware image resizing, developed by Shai Avidan, of Mitsubishi Electric Research Laboratories (MERL), and Ariel Shamir, of the Interdisciplinary Center and MERL. Every icon naturally blends with the default folder icon, so the entire look retains the original style and spirit of the OS.Īside from instant assigning icons to folders you can change folder colors the same way! Just right-click a folder you would like to colorize and select a color. FolderIco provides standard high-res icons for multiple statuses and conditions: approved, rejected, urgent and private file icons are easily available and can be quickly applied to any folder. (The FolderIco menu is fully customizable and you can add your own icons to it.)Ĭhanging a folder icon is a matter of two clicks now.
ALTERNATIVES TO IRESIZER INSTALL
After you download and install the application, it embeds to your Windows Explorer providing the quickest way to access folder icon adjustments via the right-click menu. With FolderIco you can change folder icons in a few seconds. Here is a much simpler and flexible alternative: Using built-in Windows icons may be confusing to use, because folders will look in a different way. With this method you need to make many actions and already have your own folder icons in specified format. In the opened window you can browse for the built-in icons or select your own in the ICO format. In the properties window, select the "Customize" tab Right-click onto the folder you want to change and then choose "Properties" You can change the folder icon using the standard Windows features, but this is not so easy. Didn't you ever want to make folder icons visually reflect the status of documents inside? Imagine, you look at the folder icon and immediately see if it holds important documents, files requiring urgent editing or high priority work.
