noise

I want to create a terrain-like 3D noise generator and after doing some research I came to the conclusion that Simplex Noise is by far the best type of noise to do this. I find the name quite misleading though as I have a lot of trouble finding resources on the subject and the resources I find are often not well written. What I am basically looking for is a good resource/tutorial explaining step by step how simplex noise works, and explains how to implement that into a program. I am not looking for resources explaining how to use a library or something. Richard Tingle In lue of a tutorial

This question already has an answer here: Best method to find edge of noise image 2 answers I have used adapthisteq to improve the visibility of the foreground objects. However, this seems to have created grainy noisy details. How can I remove these grainy details from the image? I have tried Gaussian blurring through imgaussfilt and while it does remove some of the grainy details, the shape of the cells in the image become less defined. The second image shows the binary image of the first image. You can use a filter that takes into consideration the edge information like bilateral filter.

I am writing some function to add noise effect on bitmap. I found similar question: Add noise effect to a drawing Bitmap outputBitmap = Bitmap.createBitmap(bitmap.getWidth(), bitmap.getHeight(), Bitmap.Config.ARGB_8888); BitmapShader shader = new BitmapShader (bitmap, TileMode.REPEAT, TileMode.REPEAT); Paint paint = new Paint(); paint.setShader(shader); Canvas c = new Canvas(outputBitmap); c.drawBitmap(bitmap, 0, 0, paint); How should i add color filter to get such a result? Could you provide somple code? i suggested that use this code. public static final int COLOR_MIN = 0x00; public static
