텐서플로우:: 작전:: 크기 조정 영역
#include <image_ops.h>
영역 보간을 사용하여 images
size
조정합니다.
요약
입력 이미지는 다양한 유형일 수 있지만 출력 이미지는 항상 부동입니다.
출력 이미지의 픽셀 값 범위는 제한된 수치 정밀도로 인해 입력 이미지의 범위와 약간 다를 수 있습니다. 출력 범위(예: [0.0, 1.0]
를 보장하려면 출력에 tf.clip_by_value
적용하세요.
각 출력 픽셀은 먼저 픽셀의 공간을 입력 텐서로 변환한 다음 공간과 교차하는 픽셀의 평균을 구하여 계산됩니다. 평균에 대한 입력 픽셀의 기여도는 공간과 교차하는 해당 영역의 비율에 따라 가중치가 부여됩니다. 이는 OpenCV의 INTER_AREA와 동일합니다.
인수:
- 범위: 범위 개체
- 이미지:
[batch, height, width, channels]
모양의 4D. - size: = 2개 요소로 구성된 1차원 int32 텐서 :
new_height, new_width
. 이미지의 새로운 크기입니다.
선택적 속성( Attrs
참조):
- align_corners: true인 경우 입력 및 출력 텐서의 4개 모서리 픽셀의 중심이 정렬되어 모서리 픽셀의 값이 유지됩니다. 기본값은 거짓입니다.

To guarantee an output range, for example `[0.0, 1.0]`, apply `tf.clip_by_value` to the output.\n\nEach output pixel is computed by first transforming the pixel's footprint into the input tensor and then averaging the pixels that intersect the footprint. An input pixel's contribution to the average is weighted by the fraction of its area that intersects the footprint. This is the same as OpenCV's INTER_AREA.\n\nArguments:\n\n- scope: A [Scope](/versions/r2.1/api_docs/cc/class/tensorflow/scope#classtensorflow_1_1_scope) object\n- images: 4-D with shape `[batch, height, width, channels]`.\n- size: = A 1-D int32 [Tensor](/versions/r2.1/api_docs/cc/class/tensorflow/tensor#classtensorflow_1_1_tensor) of 2 elements: `new_height, new_width`. The new size for the images.\n\n\u003cbr /\u003e\n\nOptional attributes (see [Attrs](/versions/r2.1/api_docs/cc/struct/tensorflow/ops/resize-area/attrs#structtensorflow_1_1ops_1_1_resize_area_1_1_attrs)):\n\n- align_corners: If true, the centers of the 4 corner pixels of the input and output tensors are aligned, preserving the values at the corner pixels. Defaults to false.\n\n\u003cbr /\u003e\n\nReturns:\n\n- [Output](/versions/r2.1/api_docs/cc/class/tensorflow/output#classtensorflow_1_1_output): 4-D with shape `[batch, new_height, new_width, channels]`.\n\n\u003cbr /\u003e\n\n| ### Constructors and Destructors ||\n|---|---|\n| [ResizeArea](#classtensorflow_1_1ops_1_1_resize_area_1a48c3b130fbd05acaed9512549485f012)`(const ::`[tensorflow::Scope](/versions/r2.1/api_docs/cc/class/tensorflow/scope#classtensorflow_1_1_scope)` & scope, ::`[tensorflow::Input](/versions/r2.1/api_docs/cc/class/tensorflow/input#classtensorflow_1_1_input)` images, ::`[tensorflow::Input](/versions/r2.1/api_docs/cc/class/tensorflow/input#classtensorflow_1_1_input)` size)` ||\n| [ResizeArea](#classtensorflow_1_1ops_1_1_resize_area_1ac1b5d48c5c77399d5198780d905281d7)`(const ::`[tensorflow::Scope](/versions/r2.1/api_docs/cc/class/tensorflow/scope#classtensorflow_1_1_scope)` & scope, ::`[tensorflow::Input](/versions/r2.1/api_docs/cc/class/tensorflow/input#classtensorflow_1_1_input)` images, ::`[tensorflow::Input](/versions/r2.1/api_docs/cc/class/tensorflow/input#classtensorflow_1_1_input)` size, const `[ResizeArea::Attrs](/versions/r2.1/api_docs/cc/struct/tensorflow/ops/resize-area/attrs#structtensorflow_1_1ops_1_1_resize_area_1_1_attrs)` & attrs)` ||\n\n| ### Public attributes ||\n|----------------------------------------------------------------------------------------------|---------------------------------------------------------------------------------------------------------|\n| [operation](#classtensorflow_1_1ops_1_1_resize_area_1a5cb2a40837fb9d975e2ca454469e5cac) | [Operation](/versions/r2.1/api_docs/cc/class/tensorflow/operation#classtensorflow_1_1_operation) |\n| [resized_images](#classtensorflow_1_1ops_1_1_resize_area_1a64b25c97b7028b2b4c93978f2e957ad4) | `::`[tensorflow::Output](/versions/r2.1/api_docs/cc/class/tensorflow/output#classtensorflow_1_1_output) |\n\n| ### Public functions ||\n|-----------------------------------------------------------------------------------------------------------------------|------------------------|\n| [node](#classtensorflow_1_1ops_1_1_resize_area_1abdc62a6906daefaa326cda016f8fbb0c)`() const ` | `::tensorflow::Node *` |\n| [operator::tensorflow::Input](#classtensorflow_1_1ops_1_1_resize_area_1a6e7fba9df05a54b4e0de2d079fa03403)`() const ` | ` ` ` ` |\n| [operator::tensorflow::Output](#classtensorflow_1_1ops_1_1_resize_area_1a15a700424a492dfe07a1777ddc6146bd)`() const ` | ` ` ` ` |\n\n| ### Public static functions ||\n|------------------------------------------------------------------------------------------------------|-------------------------------------------------------------------------------------------------------------------------------|\n| [AlignCorners](#classtensorflow_1_1ops_1_1_resize_area_1ae8ffc21c407e98bddb149275984ed3cf)`(bool x)` | [Attrs](/versions/r2.1/api_docs/cc/struct/tensorflow/ops/resize-area/attrs#structtensorflow_1_1ops_1_1_resize_area_1_1_attrs) |\n\n| ### Structs ||\n|----------------------------------------------------------------------------------------------------------|--------------------------------------------------------------------------------------------------------------------------------------------------|\n| [tensorflow::ops::ResizeArea::Attrs](/versions/r2.1/api_docs/cc/struct/tensorflow/ops/resize-area/attrs) | Optional attribute setters for [ResizeArea](/versions/r2.1/api_docs/cc/class/tensorflow/ops/resize-area#classtensorflow_1_1ops_1_1_resize_area). |\n\nPublic attributes\n-----------------\n\n### operation\n\n```text\nOperation operation\n``` \n\n### resized_images\n\n```scdoc\n::tensorflow::Output resized_images\n``` \n\nPublic functions\n----------------\n\n### ResizeArea\n\n```gdscript\n ResizeArea(\n const ::tensorflow::Scope & scope,\n ::tensorflow::Input images,\n ::tensorflow::Input size\n)\n``` \n\n### ResizeArea\n\n```gdscript\n ResizeArea(\n const ::tensorflow::Scope & scope,\n ::tensorflow::Input images,\n ::tensorflow::Input size,\n const ResizeArea::Attrs & attrs\n)\n``` \n\n### node\n\n```gdscript\n::tensorflow::Node * node() const \n``` \n\n### operator::tensorflow::Input\n\n```gdscript\n operator::tensorflow::Input() const \n``` \n\n### operator::tensorflow::Output\n\n```gdscript\n operator::tensorflow::Output() const \n``` \n\nPublic static functions\n-----------------------\n\n### AlignCorners\n\n```text\nAttrs AlignCorners(\n bool x\n)\n```"]]
