Image filtering can be grouped in two depending on the effects: Low pass filters (Smoothing) Low pass filtering (aka smoothing), is employed to remove high spatial frequency noise from a digital image. The low-pass filters usually employ moving window operator which affects one pixel of the image at a time, changing its value by some function of a local region (window) of pixels Discouraged Usage. Recommended Replacement. This example creates an ROI and uses getColor to retrieve the color of the ROI. imshow ( 'cameraman.tif' ); h = imrect (gca, [10 10 100 100]); rgb = getColor (h) Here is equivalent code, replacing the old ROI with the new ROI object and then accessing the value of the Color property of the ROI Use the imcolormaptool function to create a Choose Colormap tool. The Choose Colormap tool is an interactive colormap selection tool that allows you to change the colormap of a figure by selecting a colormap from a list of MATLAB ® colormap functions or workspace variables, or by entering a custom MATLAB expression

Click and drag the mouse to move the rectangle. Resizing the rectangle. Move the pointer over any of the edges or corners of the rectangle, the shape changes to a double-ended arrow, . Click and drag the edge or corner using the mouse. Changing the color of the rectangle imerode supports the generation of C code (requires MATLAB ® Coder™).Note that if you choose the generic MATLAB Host Computer target platform, imerode generates code that uses a precompiled, platform-specific shared library. Use of a shared library preserves performance optimizations but limits the target platforms for which code can be generated

In these examples, imread infers the file format to use from the contents of the file. You can also specify the file format as an argument to imread.imread supports many common graphics file formats, such as the Graphics Interchange Format (GIF), Joint Photographic Experts Group (JPEG), Portable Network Graphics (PNG), and Tagged Image File Format (TIFF) formats features = extractHOGFeatures(I) returns extracted HOG features from a truecolor or grayscale input image, I.The features are returned in a 1-by-N vector, where N is the HOG feature length.The returned features encode local shape information from regions within an image. You can use this information for many tasks including classification, detection, and tracking Image to be filtered, specified as a numeric array of any dimension. If the input image has more than two dimensions ( ndims (I)>2 ), such as for an RGB image, then imboxfilt performs box filtering of all 2-D planes along the higher dimensions.
