Subpixel edges and geometric fitting
Sobel/Scharr/Canny edges → subpixel refinement → RANSAC line, circle or curve fitting → geometric calculation
JIVISION offers project development and technical assessment for Pipetting, Tip and Droplet-Process Vision Monitoring. Scope: Pipette tips, liquid surfaces/drops, positions and process stages.
Pipette tips, liquid surfaces/drops, positions and process stages
Visible droplets do not establish pipetting accuracy; use gravimetry or another reference and record liquid adhering to tips.
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.
Sobel/Scharr/Canny edges → subpixel refinement → RANSAC line, circle or curve fitting → geometric calculation
RTMPose, HRNet or MediaPipe keypoints → temporal filtering → joint angles, poses and spatial relationships
Shi-Tomasi/FAST features → LK, Farneback or DIS flow; alternatively TAPIR/TAPNext/RAFT → occlusion and drift handling
Detection and tracking → polygons, crossing, distance, time-to-collision, dwell and hysteresis rules → event state machine
Provide authorized, de-identified data, device/staining/acquisition protocols, the research protocol, expert annotations, independent batch or participant splits and ethics requirements.
Result schema, algorithm or processing configuration, example outputs and evaluation records for: Pipette tips, liquid surfaces/drops, positions and process stages. 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.
Drop/step F1; position error; discovery delay
Prevent participant or source-slide leakage across training/test sets. Record annotation agreement, stratified metrics, failure cases and reproducibility parameters; use traceable references for laboratory measurements.
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.
For laboratory automation and research analysis, not disease diagnosis, screening, treatment decisions or medical-device performance claims. Clinical use requires separate applicable validation and approvals.
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.
Pipette tips, liquid surfaces/drops, positions and process stages. Deliverables: Result schema, algorithm or processing configuration, example outputs and evaluation records for: Pipette tips, liquid surfaces/drops, positions and process stages. Software format and source-code scope are agreed in the contract.
Visible droplets do not establish pipetting accuracy; use gravimetry or another reference and record liquid adhering to tips.
Task-specific measures: Drop/step F1; position error; discovery delay. Prevent participant or source-slide leakage across training/test sets. Record annotation agreement, stratified metrics, failure cases and reproducibility parameters; use traceable references for laboratory measurements.
After reviewing samples for pipette tips, liquid surfaces/drops, positions and process stages, 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.
