RyoheiHagimoto 0:0e0631af0305 113 /** @brief Image class which provides a thin layer around an IplImage.
RyoheiHagimoto 0:0e0631af0305 114
RyoheiHagimoto 0:0e0631af0305 115 The goals of the class design are:
RyoheiHagimoto 0:0e0631af0305 116
RyoheiHagimoto 0:0e0631af0305 117 -# All the data has explicit ownership to avoid memory leaks
RyoheiHagimoto 0:0e0631af0305 118 -# No hidden allocations or copies for performance.
RyoheiHagimoto 0:0e0631af0305 119 -# Easy access to OpenCV methods (which will access IPP if available)
RyoheiHagimoto 0:0e0631af0305 120 -# Can easily treat external data as an image
RyoheiHagimoto 0:0e0631af0305 121 -# Easy to create images which are subsets of other images
RyoheiHagimoto 0:0e0631af0305 122 -# Fast pixel access which can take advantage of number of channels if known at compile time.
RyoheiHagimoto 0:0e0631af0305 123
RyoheiHagimoto 0:0e0631af0305 124 The WImage class is the image class which provides the data accessors. The 'W' comes from the fact
RyoheiHagimoto 0:0e0631af0305 125 that it is also a wrapper around the popular but inconvenient IplImage class. A WImage can be
RyoheiHagimoto 0:0e0631af0305 126 constructed either using a WImageBuffer class which allocates and frees the data, or using a
RyoheiHagimoto 0:0e0631af0305 127 WImageView class which constructs a subimage or a view into external data. The view class does no
RyoheiHagimoto 0:0e0631af0305 128 memory management. Each class actually has two versions, one when the number of channels is known
RyoheiHagimoto 0:0e0631af0305 129 at compile time and one when it isn't. Using the one with the number of channels specified can
RyoheiHagimoto 0:0e0631af0305 130 provide some compile time optimizations by using the fact that the number of channels is a
RyoheiHagimoto 0:0e0631af0305 131 constant.
RyoheiHagimoto 0:0e0631af0305 132
RyoheiHagimoto 0:0e0631af0305 133 We use the convention (c,r) to refer to column c and row r with (0,0) being the upper left corner.
RyoheiHagimoto 0:0e0631af0305 134 This is similar to standard Euclidean coordinates with the first coordinate varying in the
RyoheiHagimoto 0:0e0631af0305 135 horizontal direction and the second coordinate varying in the vertical direction. Thus (c,r) is
RyoheiHagimoto 0:0e0631af0305 136 usually in the domain [0, width) X [0, height)
RyoheiHagimoto 0:0e0631af0305 137
RyoheiHagimoto 0:0e0631af0305 138 Example usage:
RyoheiHagimoto 0:0e0631af0305 139 @code
RyoheiHagimoto 0:0e0631af0305 140 WImageBuffer3_b im(5,7); // Make a 5X7 3 channel image of type uchar
RyoheiHagimoto 0:0e0631af0305 141 WImageView3_b sub_im(im, 2,2, 3,3); // 3X3 submatrix
RyoheiHagimoto 0:0e0631af0305 142 vector<float> vec(10, 3.0f);
RyoheiHagimoto 0:0e0631af0305 143 WImageView1_f user_im(&vec[0], 2, 5); // 2X5 image w/ supplied data
RyoheiHagimoto 0:0e0631af0305 144
RyoheiHagimoto 0:0e0631af0305 145 im.SetZero(); // same as cvSetZero(im.Ipl())
RyoheiHagimoto 0:0e0631af0305 146 *im(2, 3) = 15; // Modify the element at column 2, row 3
RyoheiHagimoto 0:0e0631af0305 147 MySetRand(&sub_im);
RyoheiHagimoto 0:0e0631af0305 148
RyoheiHagimoto 0:0e0631af0305 149 // Copy the second row into the first. This can be done with no memory
RyoheiHagimoto 0:0e0631af0305 150 // allocation and will use SSE if IPP is available.
RyoheiHagimoto 0:0e0631af0305 151 int w = im.Width();
RyoheiHagimoto 0:0e0631af0305 152 im.View(0,0, w,1).CopyFrom(im.View(0,1, w,1));
RyoheiHagimoto 0:0e0631af0305 153
RyoheiHagimoto 0:0e0631af0305 154 // Doesn't care about source of data since using WImage
RyoheiHagimoto 0:0e0631af0305 155 void MySetRand(WImage_b* im) { // Works with any number of channels
RyoheiHagimoto 0:0e0631af0305 156 for (int r = 0; r < im->Height(); ++r) {
RyoheiHagimoto 0:0e0631af0305 157 float* row = im->Row(r);
RyoheiHagimoto 0:0e0631af0305 158 for (int c = 0; c < im->Width(); ++c) {
RyoheiHagimoto 0:0e0631af0305 159 for (int ch = 0; ch < im->Channels(); ++ch, ++row) {
RyoheiHagimoto 0:0e0631af0305 160 *row = uchar(rand() & 255);
RyoheiHagimoto 0:0e0631af0305 161 }
