EMCVBasicImage

A wrapped basic image class.

  • [ObjC]: Means this property or method can be used on Objective-C.
  • [ObjC++]: Means this property or method can only be used on Objective-C++.

See: [EMCVImage] [EMCVSingleImage]

Property

  • [ObjC++]: _mat: A cv::Mat object. It's image data.
  • [ObjC++]: _hist: A cv::MatND object. It's histogram data.
  • [ObjC]: channalCount: How much channals in current image;
  • [ObjC]: imageSize: Get size of the image.

Instance Method

Initialization

  • [ObjC++]: initWithMat: Init a instance with a cv::Mat.
  • [ObjC++]: initWithNoCopyMat: Init a instance with a cv::Mat and will not copy memory.
  • [ObjC++]: initWithMat:cvtColor: Init a instance with a cv::Mat and color format like CV_BGR2RGB whitch is defined by OpenCV.
  • [ObjC]: initWithSize:andType:andColor: Init a empty EMCVBasicImage instance with type and color. Type must be like CV_8UC3 whitch is defined by OpenCV. Color is a RGB value array.

Others

  • [ObjC]: forEachPixelWithBlock: Enumerate each pixel and run a block with pixel's memory pointer.
  • [ObjC]: forEachPixelAtX:andY:withBlock: Run a block with the specified pixel's memory pointer.
  • [ObjC]: cvtColor: Converts image from one color space to another. the Param must be like CV_BGR2RGB whitch is defined by OpenCV. The same as cv::cvtColor.
  • [ObjC]: makeACopy: Make a copy. It will copy memory.
  • [ObjC]: splitImage: Split image's channels.
  • [ObjC]: flipWithXAxis: Flip with X axis.
  • [ObjC]: flipWithYAxis: Flip with Y axis.
  • [ObjC]: setBrightness: Set brightness with ± value.
  • [ObjC]: pyrUpWithRatio: PyrUp with a ratio.
  • [ObjC]: pyrDownWithRatio: PyrDown with a ratio.
  • [ObjC]: calHistWithSize:range: Calculate histogram using all channals with the same size and range.
  • [ObjC]: calHistWithSizes:ranges: Calculate histogram with the sizes and ranges.
  • [ObjC]: normalizeImageWithValue: Normalize image to a value.
  • [ObjC]: normalizeHistWithValue: Normalize histogram to a value.
  • [ObjC]: drawALineWithPoint:andPoint:andColor:andThickness:Draw a line with specified points, color and thickness.
  • [ObjC]: drawARectWithCenter:size:rgbColor:thickness: Draw a rect with specified center, size and thickness.
  • [ObjC]: drawARect:rgbColor:thickness: Draw a rect with specified rect and thickness.
  • [ObjC]: drawACircleWithCenter:andRadius:andColor:andThickness: Draw a circle with specified center, radius, color and thickness.
  • [ObjC]: blurWithSize: Use Normalized Box Filter to smooth a image.
  • [ObjC]: medianBlurWithSize: Use Median Filter to smooth a image.
  • [ObjC]: bilateralFilterWithDelta:andSigmaColor:andSigmaSpace: Use Bilateral Filter to smooth a image.
  • [ObjC]: gaussianBlurWithSize: Do Gaussian Blur with a specified kernel size.
  • [ObjC]: toImage: Converts image to a NSImage instance.
