Content Aware Resize

No algorithm description given

Table of Contents Introduction I/O Examples credits Algorithm Console Introduction This algorithm discovers the most important features of an image and attempts to preserve them when resizing. It does this by utilizing both both the face detection and Salnet algorithms to determine importance, and using opencv to directly crop and resize the image. I/O Input { "image":String, "output":String, "width":Int, "height":Int, "raio":Float, "binarize":Boolean } image - (required) - an input image as either a url, data connector uri ( data://, s3://, etc) or a base 64 encoded string. output - (optional) - the output data connector path to where you want to save the resized image to. defaults to data://.algo/temp/<uuid>.png width - (optional) - the desired resize width. defaults to 188 height - (optional) - the desired resize height. defaults to 265 ratio - (optional) - the weighted ratio between the effects of Saliency and Face recognition on the final centroid. A value of 0.0 means the result will entirely depend on saliency, whereas a value of 1.0 will entirely depend on face detection. Here's the exact formula used by the algorithm: centroid(x,y) = face_detection(x,y)*(ratio) + salnet(x,y)*(1-ratio) . defaults to 0.5 binarize - (optional) - an optional flag that if defined, forces the output to be returned as a base64 encoded string . defaults to false Output { "output":String } output - the resized image data collection URI. Examples Example 1 Input { "height":1500, "width":400, "ratio":0.65, "output":"data://.algo/temp/thumb.jpg", "image":"http://i.imgur.com/NU7t6yB.jpg" } Output { "output":"data://.algo/temp/thumb.jpg" } Example 2 Input { "image":"https://i.redd.it/mdog3luiawcy.jpg", "width":400, "height":1500 } Output { "output":"data://.algo/temp/77d3e783-b7fb-4390-b789-af321b69dc89.png" } Credits This algorithm utilizes opencv for image manipulation and editing, dlib's face detection , and deeplearning's Salnet .

Internet access

This algorithm has Internet access. This is necessary for algorithms that rely on external services, however it also implies that this algorithm is able to send your input data outside of the Algorithmia platform.


Calls other algorithms

This algorithm has permission to call other algorithms. This allows an algorithm to compose sophisticated functionality using other algorithms as building blocks, however it also carries the potential of incurring additional royalty and usage costs from any algorithm that it calls.


To understand more about how algorithm permissions work, see the permissions documentation.
