That is: 3 | * [getAffineTransform](https://docs.opencv.org/2.4/modules/imgproc/doc/geometric_transformations.html?highlight=getaffinetransform#getaffinetransform) 4 | * [warpAffine](https://docs.opencv.org/2.4/modules/imgproc/doc/geometric_transformations.html?highlight=getaffinetransform#warpaffine) 5 | * [getPerspectiveTransform](https://docs.opencv.org/2.4/modules/imgproc/doc/geometric_transformations.html?highlight=getaffinetransform#getperspectivetransform) 6 | * [warpPerspective](https://docs.opencv.org/2.4/modules/imgproc/doc/geometric_transformations.html?highlight=getaffinetransform#warpperspective) 7 | 8 | Implementation is provided in an educative simplistic way with a lot of comments, visualization, and explanations. 9 | ## References 10 | * https://math.stackexchange.com/questions/296794/finding-the-transform-matrix-from-4-projected-points-with-javascript 11 | * https://stackoverflow.com/questions/8925569/perspective-projection-4-points 12 | -------------------------------------------------------------------------------- /LICENSE: -------------------------------------------------------------------------------- 1 | MIT License 2 | 3 | Copyright (c) 2019 Oleh 4 | 5 | Permission is hereby granted, free of charge, to any person obtaining a copy 6 | of this software and associated documentation files (the "Software"), to deal 7 | in the Software without restriction, including without limitation the rights 8 | to use, copy, modify, merge, publish, distribute, sublicense, and/or sell 9 | copies of the Software, and to permit persons to whom the Software is 10 | furnished to do so, subject to the following conditions: 11 | 12 | The above copyright notice and this permission notice shall be included in all 13 | copies or substantial portions of the Software. 14 | 15 | THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR 16 | IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, 17 | FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
