Crop the given image and zoom to the specified size.
Public Functions
-
ResizedCrop(int32_t top, int32_t left, int32_t height, int32_t width, const std::vector<int32_t> &size, InterpolationMode interpolation = InterpolationMode::kLinear)
Constructor.
Note
If the input image is more than one, then make sure that the image size is the same.
- Parameters
top – [in] Horizontal ordinate of the upper left corner of the crop image.
left – [in] Vertical ordinate of the upper left corner of the crop image.
height – [in] Height of cropped image.
width – [in] Width of cropped image.
size – [in] A vector representing the output size of the image. If the size is a single value, a squared resized of size (size, size) is returned. If the size has 2 values, it should be (height, width).
interpolation – [in] Image interpolation mode. Default: InterpolationMode::kLinear.
InterpolationMode::kLinear, Interpolation method is blinear interpolation.
InterpolationMode::kNearestNeighbour, Interpolation method is nearest-neighbor interpolation.
InterpolationMode::kCubic, Interpolation method is bicubic interpolation.
InterpolationMode::kArea, Interpolation method is pixel area interpolation.
InterpolationMode::kCubicPil, Interpolation method is bicubic interpolation like implemented in pillow.
Example/* Define operations */ auto decode_op = vision::Decode(); auto resized_crop_op = vision::ResizedCrop(128, 128, 256, 256, {128, 128}); /* dataset is an instance of Dataset object */ dataset = dataset->Map({decode_op, resized_crop_op}, // operations {"image"}); // input columns
