1. function prototype: iplimage * cvloadimage (const char * filename, int flags = cv_load_image_color); filename: name of the file to be read (including the suffix); flags: specify the color and depth of the image to be read: The specified color can be converted into three channels (cv_load_image_color), one channel (cv_load_image_grayscale), or remain unchanged (cv_load_image_anycolor ). Specify whether or not the input image is converted into 8 bits per pixel for each color channel (same as in early versions of opencv), or remains the same as the input image. Select cv_load_image_anydepth. The input image format can be 8-bit unsigned, 16-bit unsigned, 32-bit signed, or 32-bit floating point. If the input contains a conflicting sign, a smaller number is used. For example, cv_load_image_color | cv_load_image_anycolor is loaded into the 3-channel diagram. Cv_load_image_anycolor and cv_load_image_unchanged are equivalent. However, cv_load_image_anycolor can be used with cv_load_image_anydepth, so cv_load_image_unchanged is no longer used. If you want to load the most authentic image, select cv_load_image_anydepth | cv_load_image_anycolor. The cvloadimage function reads an image from a specified file and returns a pointer to the image. Currently, the following file formats are supported: Windows bitmap files-BMP, dib; JPEG files-JPEG, JPG, jpe; portable network images-PNG; portable image formats-PBM, PGM, and ppm; sun rasters-Sr, Ras; TIFF file-Tiff, Tif; openexr HDR Image-EXR; JPEG 2000 image-JP2. 2. How to Use the cvloadimage function: cvloadimage (filename,-1); the number of original channels for reading the image cvloadimage (filename, 0) by default; forced conversion to read the image as a grayscale image cvloadimage (filename, 1); read color legend: forcibly convert the read image to grayscale image display # include Cvloadimage function analysis cvloadimagem () function
