Risks & Mitigations
- OCR variability by country/language — mitigate with multi-engine OCR and configurable parsing rules.
- Increased latency from liveness checks — use passive-first approach and fall back to active only when needed.
- Privacy concerns — minimize stored PII, encrypt, and implement strict retention/purge policies.
6.3 Custom Applications
Developers can deploy Qt‑based or Python‑based apps:
- Toolchain – Use the provided Docker image
midv/dev:latest(contains cross‑compiler, Qt, and SDK). - Deploy – Copy the compiled binary to
/opt/apps/via SCP. - Register – Edit
/etc/midv/apps.confto add a menu entry.
Documentation for the SDK is located in the /usr/share/midv/sdk/ folder on the device.
4. Preprocessing and geometric normalization
Goals:
- Detect the document region
- Warp to a canonical rectangle for OCR
Steps:
- Document detection (coarse) — use classical or learned methods.
- Classical: edge detection + contour filtering by area and aspect ratio.
- Learned: train a detector (e.g., Faster R-CNN or YOLO) with quadrilateral-to-bbox conversion.
Classical quad detection sketch:
gray = cv2.cvtColor(img, cv2.COLOR_RGB2GRAY)
blur = cv2.GaussianBlur(gray, (5,5), 0)
ed = cv2.Canny(blur, 50, 150)
cnts, _ = cv2.findContours(ed, cv2.RETR_LIST, cv2.CHAIN_APPROX_SIMPLE)
# keep largest contour approximating 4 points
- Perspective transform to rectify:
import numpy as np
def warp_quad(img, quad, out_size=(1024, 720)):
src = np.array(quad, dtype='float32')
dst = np.array([[0,0],[out_size[0]-1,0],[out_size[0]-1,out_size[1]-1],[0,out_size[1]-1]], dtype='float32')
M = cv2.getPerspectiveTransform(src, dst)
return cv2.warpPerspective(img, M, out_size)
- Color normalization for OCR: contrast limited adaptive histogram equalization (CLAHE) or simple gamma correction helps.
Getting Started – How to Deploy MIDV‑679
- Assess Your Workload – Identify data sources, compute intensity, and latency requirements.
- Select Modules – Choose the appropriate mix of AI‑Core, GPU, FPGA, or storage cards from the catalog.
- Integrate with Existing Infrastructure – Use the universal backplane to connect to your network fabric (e.g., 400 Gb/s Ethernet, InfiniBand).
- Install MiraOS & Dashboard – Follow the one‑click installer; the system auto‑detects modules and optimizes the data pipeline.
- Deploy Analytics – Pull from the Marketplace or develop custom pipelines via the MiraSDK.
- Monitor & Optimize – Use the built‑in AI Power Manager to continuously trim energy use while meeting SLAs.
Pro tip: Start with a “Pilot Node” (a single chassis) in a low‑risk environment, then scale out horizontally as you validate performance.
11. Robustness: common failure modes and fixes
- Partial occlusion: augment training with occluders; use models tolerant to missing corners; fallback to partial detection + predictive cropping.
- Strong perspective distortion: include aggressive perspective transforms in augmentation.
- Low light and blur: include motion blur and varying noise in augmentation.
- Background clutter: train detector to distinguish document edges from similar textures; use background replacement augmentation.
- Overfitting to templates: diversify training with synthetic variants—fonts, stamps, holograms, and wear.
