geometric images art

a brief introduction to geometric transformationUnlike point operations, it can ChangeIn the image the spatial relationship between pixels, this operation can be regarded as PixelIn the image MoveThe process. Definition: g (x,y) =f (x,y) =f[a (x,y), B (X,y)] g (x, Y) = f (x, y) = F[a (x, y), B (x, y)], where F (x,y) f (x, y) represents the input image, G (x,y) g (x, y) represents the output image, A (X,y) a (x, y) and B (x,y) b (x, y) represent space

To give you illustrator software users to detailed analysis of the plot to draw the effect of linear fringe geometric art of the tutorial. Tutorial Sharing: First, create art brushes To make a stripe pattern, the first thing we need to think about is what tools are used to achieve it more quickly. Because such as stripes, dots, square

mapped to () of the output image. Then) what is the pixel value? To solve the above two problems, you can use"Backward ing", The output image coordinates are used to calculate and change the coordinates corresponding to the coordinates in the original image. In this way, each pixel of the output image can find the unique corresponding pixel through the ing relationship in the original image, without the incomplete and overlapping mappings. Therefore, backward ing is generally used to process

Geometric Transformation Geometric transformation can be seen as a change in the space position of an object (or pixel) in an image, or the movement of pixels. Geometric operations require two steps: spatial transformation and gray-level difference. pixels map to new coordinate positions by transformation. The new positions may be between several pixels, that is,

vertices and regard each vertex as a range. Using the bounds. extend method to combine all the ranges is the external rectangle we need. The extend method is as follows: CanvasSketch.Bounds.prototype.extend = function (bounds) { if(this.left > bounds.left) { this.left = bounds.left; } if(this.bottom > bounds.bottom) { this.bottom = bounds.bottom; } if(this.right In this method, we compare the size and assign the appropriate location information to the bounds to be

Based on opencv2, two simple geometric
