Reference alignment and difference analysis
NCC/ZNCC, phase correlation or ECC → ORB/AKAZE/SIFT features → RANSAC homography → SSIM or image differences
JIVISION offers project development and technical assessment for Object Removal, Cargo Loss and Scene-Change Detection. Scope: Removed objects, changed regions, timestamps and comparison images.
Removed objects, changed regions, timestamps and comparison images
Background updates must not absorb real removal events; business records or people distinguish authorized moves from exceptions.
These are candidate implementation paths. Establish a baseline on real samples, then select or combine methods for imaging, speed and deployment constraints. Model names do not imply measured project results.
NCC/ZNCC, phase correlation or ECC → ORB/AKAZE/SIFT features → RANSAC homography → SSIM or image differences
RT-DETR, RTMDet, YOLOX, PP-YOLOE or rotated-box detection → non-maximum suppression and confidence thresholds → task rules
Object detection → ByteTrack, OC-SORT, BoT-SORT or Norfair association → Kalman filtering and track management
Detection and tracking → polygons, crossing, distance, time-to-collision, dwell and hysteresis rules → event state machine
Provide camera layouts, authorized video, target sizes, day/night samples, region/event definitions, concurrent streams, alert-review workflows and retention periods.
Result schema, algorithm or processing configuration, example outputs and evaluation records for: Removed objects, changed regions, timestamps and comparison images. Software format and source-code scope are agreed in the contract.
Specify input formats, output fields, coordinates/units, error states, versions and invocation methods. Define review and failure handling. The statement of work determines the exact scope of source code, executables, model files or analysis reports.
Removal-event recall; false positives; minimum object
Evaluate events rather than only frames: misses, false alerts per hour, duration error, alert latency and recovery after occlusion. Include empty scenes and hard negatives.
These are measures to agree and test, not achieved-performance claims. Freeze samples, reference truth, thresholds and hardware/software versions before acceptance; report subgroup results and failures, identifying under-sampled conditions as uncovered.
Agree targets, stations, inputs and responsibilities in a statement of work, separating required and excluded conditions.
Use representative samples to test critical risks, document feasibility/failures and scope the next-stage estimate.
Implement agreed functions and interfaces with configuration/change records; use offline replay before authorized device or site integration.
Retest against individual measures and hand over contracted artifacts with known limits; manage maintenance, expansion and changeovers as subsequent work packages.
Use data minimization, anonymization and access controls as needed. Do not infer sensitive traits, emotions or medical status from appearance; review alerts and retain existing safety measures.
Candidate technologies are not license clearance. Check code, model weights, training data and dependency versions separately. Replace, license or exclude components unsuitable for the intended commercial delivery. Customer data is not used for public training by default.
Removed objects, changed regions, timestamps and comparison images. Deliverables: Result schema, algorithm or processing configuration, example outputs and evaluation records for: Removed objects, changed regions, timestamps and comparison images. Software format and source-code scope are agreed in the contract.
Background updates must not absorb real removal events; business records or people distinguish authorized moves from exceptions.
Task-specific measures: Removal-event recall; false positives; minimum object. Evaluate events rather than only frames: misses, false alerts per hour, duration error, alert latency and recovery after occlusion. Include empty scenes and hard negatives.
After reviewing samples for removed objects, changed regions, timestamps and comparison images, equipment conditions and interfaces, scope validation, development, deployment and acceptance separately. Data coverage, site changes and delivery rights affect the estimate; no fixed performance or schedule is promised before assessment.
