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 Grain, Bean and Nut Shape and Quality Grading. Scope: Grain/bean/nut counts, dimensions, shape, color and grades.
Grain/bean/nut counts, dimensions, shape, color and grades
Sample varieties, broken and touching kernels separately; shape grades do not establish nutrition or food-safety measures.
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
White balance and color-chart calibration → Lab/Delta E 2000 → LBP/GLCM/Gabor features → SVM or random forest
U-Net, DeepLabV3+, SegFormer or Mask2Former → connected components and morphology → region measurements
Provide species/varieties and batches, visible-trait or packaging criteria, seasonal/lighting samples, line/acquisition parameters, experimental controls and quality-review workflows.
Result schema, algorithm or processing configuration, example outputs and evaluation records for: Grain/bean/nut counts, dimensions, shape, color and grades. 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.
Count error; dimension error; grading accuracy
Split tests by variety, batch, season and device. Evaluate appearance, dimensions/counts and packaging interfaces separately; chemical or biological measures require independent reference tests.
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.
Visible anomalies do not establish disease cause, efficacy, sterility or food safety; relevant specialists must review agronomic and animal-health interpretations.
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.
Grain/bean/nut counts, dimensions, shape, color and grades. Deliverables: Result schema, algorithm or processing configuration, example outputs and evaluation records for: Grain/bean/nut counts, dimensions, shape, color and grades. Software format and source-code scope are agreed in the contract.
Sample varieties, broken and touching kernels separately; shape grades do not establish nutrition or food-safety measures.
Task-specific measures: Count error; dimension error; grading accuracy. Split tests by variety, batch, season and device. Evaluate appearance, dimensions/counts and packaging interfaces separately; chemical or biological measures require independent reference tests.
After reviewing samples for grain/bean/nut counts, dimensions, shape, color and grades, 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.
