OB_028_Despiece_Numerado

Status

Status:: Under review


1. Operation data

Internal number: OB_028
Operational regime: Translation Between Representation Systems
Source image: Digital photograph

Operational description:
A digital photograph is segmented into regions and translated into the visual language of a technical exploded view. Each region retains its photographic pixels, but begins to function as a separate and potentially identifiable part through contours, assembly lines, marks, and numbering.

The mediation is algorithmic, but the primary regime is one of translation: the image ceases to present itself as a continuous photographic surface and begins to be read as a component diagram.


2. Tools

Tools / medium:

  • Python
  • OpenCV
  • NumPy
  • scikit-image, SLIC segmentation

Script: OB028 despiece numerado.py
Dependencies: requirements.txt
Test note: OB028 NOTA.md
Parameters per result: OB028 PARAMETROS RESULTADOS.txt


3. Procedure and variables

Procedure:

  1. Proportionally reduce the image to speed up processing.
  2. Segment the photograph into visual regions.
  3. Extract the pixels corresponding to each region.
  4. Calculate a displacement direction and distance for each part.
  5. Distribute the parts across quantized directions and layers.
  6. Optionally incorporate contours, lines, origin points, and numbering.
  7. Crop excess outer space without eliminating parts.

Controlled variables:

  • Approximate number of parts
  • Compactness and smoothing of the segmentation
  • Explosion distance and variation
  • Number of directions and layers
  • Presence of ghost image
  • Guide lines, contours, marks, and numbering
  • Maximum processing size

Uncontrolled / accidental variables:

  • Specific shape of the detected regions
  • Voids produced between parts
  • Overlaps and accumulations between parts and lines
  • Degree of local recognition of each fragment
  • Mental reconstruction performed by the observer

Crisis / threshold according to my perception

Pending selection.


6. Crisis and formal-perceptual reading

The operation affects continuity, position, the relationship between part and whole, recognition, and the reading of the support:

The parts remain photographic and retain recognizable information from the original technical image, but they no longer occupy a continuous surface. The scene oscillates between photograph and assembly diagram: it can be mentally reconstructed, although its unity is subordinated to the reading of separate, numbered, and displaced components.

The crisis appears when the parts still allow the photographic origin to be recognized, but the whole is perceived first as an inventory, diagram, or technical manual.


7. Final evaluation and artistic reference

Operation notes / what I learned:
The algorithm alone does not constitute the regime of the operation. Segmentation and displacement are means to translate a raster photograph into the representation system of a numbered technical exploded view.
