UIImage masking problems iOS 7

I have heavily borrowed (standard) code which applies a grayscale UIImage mask to a UIImage. - (void) maskImage:(UIImage *)image withMask:(UIImage *)maskImage { CGImageRef imageRef = image.CGImage; // main UIImage CGImageRef maskRef = maskImage.CGImage; // grayscale UIImage mask CGImageRef mask = CGImageMaskCreate(CGImageGetWidth(maskRef), CGImageGetHeight(maskRef), CGImageGetBitsPerComponent(maskRef), CGImageGetBitsPerPixel(maskRef), CGImageGetBytesPerRow(maskRef), CGImageGetDataProvider(maskRef), NULL, false); CGImageRef masked = CGImageCreateWithMask(imageRef, mask); maskedImage = [UIImage

OpenCV Binary Image Mask for Image Analysis in C++

由 风格不统一 提交于 2019-12-03 04:16:56
I'm trying to analyse some images which have a lot of noise around the outside of the image, but a clear circular centre with a shape inside. The centre is the part I'm interested in, but the outside noise is affecting my binary thresholding of the image. To ignore the noise, I'm trying to set up a circular mask of known centre position and radius whereby all pixels outside this circle are changed to black. I figure that everything inside the circle will now be easy to analyse with binary thresholding. I'm just wondering if someone might be able to point me in the right direction for this sort

Search-Plugin for Eclipse

问题 i have written am Eclipse-plugin and now need to extend it with a search functionality. I know that Eclipse has a search feature, but it does only search the workspace and what i need is to look after matches within my own plugin and than to show the result in a tree structure. Is there any examples of search-plugins for Eclipse? I would appreciate a link of some hint :D 回答1: Check out the org.eclipse.search.searchPages extension. 来源： https://stackoverflow.com/questions/10219441/search-plugin

Applying an SVG Radial Gradient Mask to Multiple Items

由 痴心易碎 提交于 2019-12-02 16:06:13
问题 I have a number of differently colored and sized svg circles that I would like to apply a radial gradient mask to. Is there a way to define a single mask that is applied to each circle by stretching it to match that circle's size? Here is what I've come up with so far: <radialGradient id="radialGradient" cx=".5" cy=".5" r=".5"> <stop offset="0%" stop-color="white" stop-opacity="0"/> <stop offset="100%" stop-color="white" stop-opacity="1"/> </radialGradient> <mask id="radialMask" maskUnits=

how to color mask in c

由 限于喜欢 提交于 2019-12-02 08:15:19
how do you color mask a 32 bit unsigned integer for the red, green, and blue values is it like this? (color_to_be_masked>>8) This should get you the result you want: short red = (color >> 16) & 0xFF; short green = (color >> 8) & 0xFF; short blue = (color) & 0xFF; "It depends", namely on which bits are which color. Often they're mapped "backwards", so that Red is in the lower-most bits, green in the "middle", and blue on top (sometimes followed by alpha, if that is being used). Assuming 8 bits per component, you would have: uint32_t abgr = 0x80eeccaa; /* Or whatever. */ const uint8_t red = abgr

Qt: Extract intensity values clipped by a region of interest polygon

由 做~自己de王妃 提交于 2019-12-02 07:25:43
Based on a grayscale image and an ordered closed polygon (may be concave), I want to get all grayscale values that lie inside a region of interest polygon (as likewise described in SciPy Create 2D Polygon Mask ). What is the most performant realisation of that in Qt 4.8? Endpoint should be some kind of QList<double> . Thanks for your advices. In addition, is it possible to compute a floating point mask (e.g. 0 for outside the polygon, 0.3 for 30% of the pixel area is within the polygon, 1 for completely inside the polygon)? However, that's just an extra, endpoint would be QPair<double, double>
