Decapod 0.4: Camera Calibration and Bug Fixes

Decapod 0.5

UI Development:

• Remove Stitching if required (see: DECA-100)
• Accessibility improvements
  • DECA-84
  • DECA-74
  • DECA-77
  • DECA-78

Server:

• DECA-98 File system import (finish mock server consolidation). See Decapod 0.3 Design under "Import File Folder".

Design:

• Generate Stereo Calibration wireframes if necessary (check with progress / velocity of 3D stereoi dewarp at this time).

"0.6 Release" - Automatic Post-Capture Processing and Performance

• Speed up capture time
  • Measure capture and stitching performance.
  • Should we process large resolution images post capture or on export (and use scaled versions post-capture?).
• Early 3D dewarping
• Better font generation
• More usable PDFs
  • basic automated image QA: image rotation, binarization, content area detection. See Post-Capture Processing

"1.0 Release"

Numbers in brackets indicate priority. (1) = highest. (3) = lowest.

Book management

See Decapod Dashboard Wireframe.

Related to mock server "session" management?

• begin a book (1) (Unscheduled, related to mock server sessions?)

• list of all books (2) (Unscheduled)
• resume a book (probably the default action) (2) (Unscheduled)
• inport Decapod book from disk

• book-specific operations:
  • delete, (3) (Unscheduled)
  • export, (3) (Unscheduled)
  • editing metadata, (3) (Unscheduled)
  • general information (size, location) (3) (Unscheduled)

Calibration

Early Wireframe

booklib-style (1) (Release 0.5)

• camera rotation: test pictures with both cameras, may need to reorient pages (via software transform)
• identifying left page-right page cameras
• book positioning, s.t. individual pages are fully captured (may involve repositioning book and/or cameras)
• possibly doable in one-step

stereo (1) (Release 0.5 or Release 0.6)

• camera position information: multiple surface pictures (live preview likely not available)
• ensuring book spread is in complete view for both cameras (each camera has to capture both pages fully)
  general
• camera connections & support

Capture/editing/page-level management

• manual capture: (1)
  • keyboard (Release 0.5)
  • mouse (Release 0.3)
  • pedal input (Unscheduled)
• delete pages (1) (Release 0.3, 0.4)
• reorder pages:
  • near-reorder (Release 0.3) (1)
• recalibration (1) (Release 0.5)
• progress indication (possibly; unless we backload all the heavy processing and deal with downscaled images during user workflow)/feedback (1)
• Stereo dewarp (1) (Release 0.6)
• Post-capture Quality control: automatic binarizing, book frame, content bounding, deskewing automatically (1)
  • See Post-Capture Processing)

• auto-capture (time interval) (2) (unscheduled)
• live preview, if supported (2) (unscheduled)
• document metadata (2) (unscheduled)
• undo delete/reorder (2) (unscheduled)

• Post-capture Quality control: manual interaction (hence UIs) may be needed if results are poor.* insertion* (2) (unscheduled)
  • Stereo rotation correction. (2) (unscheduled)
  • See Post-Capture Processing)

• zoom/loupe/100% crop (3) (unscheduled)
• recapture* (3) (unscheduled)
• draggable Capture insert position
• grid and list views
• recapture

• Thumbnails: Post Capture Processing indicators
  • Image in Queue
  • Image being processed
  • Image processed

• Page Preview:
  • "Click anywhere to capture" control
  • Display "raw" left and right images if not processed.
  • Display processed images if processed

*Bounding boxes:

• • Left and right bounding boxes
  • Single bounding box
  • Apply-left bounding box to subsequent left pages.
  • Apply-right bounding box to subsequent right pages.
  • Collision detection and error message.

Export (could happen at book management or capture stage)

• Export to PDF:
  • pdf-image (1) (Release 0.3)
  • pdf with images and ocr (1) (Release 0.6)
  • pdf with generated fonts*(1)* (Release 0.6)

  • processed PNGs
  • Dewarped TIFFs (no other processing).

• Export to Decapod formats:
  • Full Decapod package
