  • Enable batching on MMY model

r230828

Improvements

  • Made LP rectification in VehicleAnalytics optional.
  • Improved debug rendering of inference results.
  • Optimization: More inferences operate on original image + ROI, rather than on generated crops.

Fixes

  • Fix excessive CPU consumption in pipelines with ValueSource/BooleanSwitchMuxer combo.

r230807

New

  • Car MMY Model updated to v51.4
  • Added pipeline for vehicle classification with optional detector stage (VehicleRecognition)
  • Update color and LP state models

r230713

New

  • Car MMY Model updated to v51.3

Improvements

  • Temporarily disable GPU image processing on intake: the CPU implementation is slightly faster

Fixes

  • Fix bug in Car MMY Model (v51.3) labels
  • D3TModelsPrep: incorrect batch size was used, resulting in CUDA engine rebuild on a first run.
  • Fix loading of CUDA libraries on Windows, when GPU image processing on intake is enabled.
  • Fix Windows failing to use TensorRT, due to newly introduced cuDNN dependency, after r230705

r230710

Fixes

  • Fix NPP functionality on Jetson 5.1+ (missing CUDA/NPP symlinks)
  • Reenable NVMPI on Jetpack 5.1+

r230705

New

  • Car MMY Model updated to v51.2
  • sh-event-processing update to 1.3.12 adding per class debounce (removal of unwanted input noise) functionality.
  • x86_64: Upgrade CUDA to 11.4, TensorRT to 8.5, cuDNN to 8.6
  • Introduce a build for Jetpack 5.1 on Orin hardware
  • Orin image is about 50% larger (NVIdia now prefers CUDA, cuDNN and TensorRT as part of the image, rather than shared from the host)
  • NVMPI decoder is currently disabled on Orin (will be reenabled as soon as possible)

r230605

New

  • Car MMY Model updated to v51.0

Improvements

  • VehicleAnalytics/TrafficAnalytics: disable hardware decoder in Folder Watch mode. This solves initialization errors and/or crashes with Progressive/yuv444 jpeg.

r230525

New

  • ALPR: implement new clustering algorithm for stacked characters

Improvements

  • VehicleAnalytics: change default detection model from gen5es to gen6es

Fixes

  • MediaStreamReader: Fix intermittent crash at pipeline termination / process exit

r230522

New

  • Car MMY Model updated to v50.7

Fixes

  • MediaStreamReader: fixed a regression causing slower processing for FolderWatch pipelines (introduced in r230419)

r230508

New

  • Support for previously deprecated BoxFilter configuration method had been removed.

Improvements Fixes

  • ALPR: Temporarily disable multi-row plates detection and processing. This will be restored when an improved algorithm is available
  • ALPR: Eliminate an optional extra tight crop inference. It shows no benefit with the gen5/gen6 detection models.
  • MediaStreamReader: when specifying seek position, some audio frames prior to that position were output

r230419

Improvements

  • MediaRecorder: use 0-based timestamps by default. This specifically helps with fixing playback issues of recorded videos in QuickTime.

Fixes

  • Fix intermittent crash on process exit, if CUDA decoder was used

r230417

Note: This release supersedes r230404, r230405

New

  • Car MMY Model updated to v50.6

Fixes

  • NVMPI decoder on Jetson caused a crash on some H264 sources

r230405

Note: This release supersedes r230404

Fixes

  • MediaRecorder: keyframe flag was sticky, applying to packets that aren't keyframe.

r230404

New

  • Car MMY Model updated to v50.5
  • sh-event-processing update to 1.3.10 adding intersectionLocation and updateCount reset on presence sensors.

Improvements

  • Add GNU time to ARM Docker image
  • Jetson: using NVMPI video decoder by default, resulting in performance improvemements
  • MediaStreamReader: use 0-based timestamps for recorder by default

Fixes

  • MediaRecorder: fix recording when source stream doesn't have an audio track
  • MediaRecorder: fix resulting mp4/mov files not being playable in QuickTime

r230320

_Note: This release supersedes r230317

New

  • Car MMY Model updated to v50.4

Improvements

  • Object Detector: remove possible throughput bottleneck when cascading is enabled
  • VehicleAnalytics: replace lptEnableCascading pipeline option (default: true) with lptPreferAccuracyToSpeed (default: false). Cascading and other algorithmic approaches yield minimal (up to 3%) and input-dependent benefit at a significant performance cost (up to 50%)
  • Add GNU time to x86 Docker image
  • Add peak memory reporting to runPipeline/runPipelineSet commands (Windows)
  • Refactor Redactor's pipelines
  • Core modification in pipeline scheduling/buffering algorithm
  • Refactoring of MediaStreamSource/MediaRecorder nodes to support audio streams

r230224

Improvements

  • Make NPP enabled by default (SIO_NPP_ENABLE default to 1) on all available platforms

r230217

Improvements

  • Further optimizing inference preparation on nVidia platforms

r230210

New

  • PrepareInferenceInput pipeline node has been removed - the functionality is now handled by inference nodes
  • Car MMY Model updated to v50.3

Improvements

  • Inference speed-up
    • using hardware optimized libraries (IPP, NPP) for end-to-end inference prep
    • in case of NPP, minimizing host-to-device transitions
    • optimizing buffer allocations and pooling

Fixes

  • Fix a rare crash on pipeline initialization/startup

  • TensorRT: allow batched inference execution for models supporting it
  • Update character and object detection models to support batch inference in TensorRT

Improvements

  • SIO_NPP_ENABLE environment variable controls use of NPP for inference preparation. Defaults to 1 on Intel, 0 on other platforms.
  • SIO_IPP_ENABLE environment variable controls use of IPP for inference preparation. Defaults to 1 on Intel, 0 on other platforms.
  • Improve pipeline flow by removing output limiters from intermediate nodes
  • VehicleAnalytics/TrafficAnalytics: File-based pipeline now reads frames asynchronously by default
  • Utilize NPP for color conversion and initial resize during input ingestion

Fixes

  • Fixed a bug in NPP-based inference preparation, which could cause a corrupt image to be used by inference
  • VehicleAnalytics/TrafficAnalytics: Fix a possible race condition between inference and ImageDraw node (when enabled): frame could be modified prior to/during inference.

r230109

  • Internal development release; CI pipeline changes.

r230103

New

  • Car MMY model updated to v50.0

Improvements

  • TensorRT: refactor to lay ground for future optimizations

  • iOS samples: remove no longer used frameworks

Fixes

  • Fix failure to determine model location, when ran with CWD different from SIO install path
