pastec_response: Parse Pastec image search results

In mdlincoln/PastecR: Wrapper for the Pastec Image Search and Recognition Engine API

Description

These functions access the different components of the response to a successful Pastec image query.

Usage

bounding_rects(pastec_response)

image_ids(pastec_response)

scores(pastec_response)

tags(pastec_response)

results_as_data_frame(pastec_response)

Arguments

pastec_response

The list returned by search_image.

Functions

• bounding_rects: A data.frame with the bounding box dimensions and origin for the match.

• image_ids: A vector of returned IDs.

• scores: A vector of similarity scores.

• tags: A vector of tags.

• results_as_data_frame: A data.frame with one row per search result:

  height

  integer. The height of the bounding box in the matched image.

  width

  integer. The width of the bounding box in the matched image.

  x

  integer. The origin the bounding box in the matched image.

  y

  integer. The origin of the bounding box in the matched image.

  image_id

  integer. The Pastec image IDs matched.

  scores

  integer. The image match score.

  tags

  list. A character list with any tags associated with the image.
