# qtimlpostprocess Source: [https://docs.qualcomm.com/doc/80-70022-50SC/topic/qtimlpostprocess.html](https://docs.qualcomm.com/doc/80-70022-50SC/topic/qtimlpostprocess.html) qtimlpostprocess 是一个可自定义的插件，它提供了一个库接口，用于对推理插件的张量输出进行后处理。后处理库仅负责解析张量并生成预测输出模式列表。该插件管理模块的执行、输出生成（ML 元数据或图像蒙版）、批处理、ML 暂存和其他相关任务。 Figure : 使用 qtimlpostprocess 的 GstBuffer 工作流 Layer_2 Sheet.2 Sheet.3 Sheet.4 后处理插件 后处理插件 Sheet.5 settings.json可选 settings.json（可选） Sheet.6 yolov8.label yolov8.label Sheet.7 label.json label.json Sheet.8 {“confidence”, 65, “nms-threshold”, 0.5} {“confidence”, 65,“nms-threshold”, 0.5} Sheet.10 无标签 人 自行车 汽车 摩托车 飞机 公交车 火车 卡车 船 红绿灯 消防栓 路牌 停止标志 停车计时器 凳子 鸟 猫 狗马 unlabeledpersonbicyclecarmotorcycleairplanebustraintruckboattraffic lightfire hydrantstreet signstop signparking meterbenchbirdcatdoghourse Sheet.12 {”id”, 1, “color”, “0x00FF00FF”, “label”, “unlabeled” }, {”id... {”id”, 1, “color”, “0x00FF00FF”, “label”, “unlabeled” },{”id”, 2, “color”, “0x00FF00FF”, “label”, “person” },{”id”, 3, “color”, “0x00FF00FF”, “label”, “bicycle” },{”id”, 4, “color”, “0x00FF00FF”, “label”, “car” },{”id”, 5, “color”, “0x00FF00FF”, “label”, “motorcycle” },{”id”, 6, “color”, “0x00FF00FF”, “label”, “airplane” },{”id”, 7, “color”, “0x00FF00FF”, “label”, “bus” },{”id”, 8, “color”, “0x00FF00FF”, “label”, “train” },{”id”, 9, “color”, “0x00FF00FF”, “label”, “truck” },{”id”, 10, “color”, “0x00FF00FF”, “label”, “boat” },{”id”, 11, “color”, “0x00FF00FF”, “label”, “traffic light” },{”id”, 12, “color”, “0x00FF00FF”, “label”, “fire hydrant” },{”id”, 13, “color”, “0x00FF00FF”, “label”, “street sign” },{”id”, 14, “color”, “0x00FF00FF”, “label”, “stop sign” },{”id”, 15, “color”, “0x00FF00FF”, “label”, “parking meter” },{”id”, 16, “color”, “0x00FF00FF”, “label”, “bench” },{”id”, 17, “color”, “0x00FF00FF”, “label”, “bird” },{”id”, 18, “color”, “0x00FF00FF”, “label”, “cat” },{”id”, 19, “color”, “0x00FF00FF”, “label”, “dog” },{”id”, 20, “color”, “0x00FF00FF”, “label”, “horse” } Sheet.15 标签解析器 标签解析器 Sheet.16 输入端口 neural-network/tensors 输入端口neural-network/tensors Sheet.18 输出端口 video/x-raw audio/x-raw 输出端口video/x-rawaudio/x-raw Sheet.20 后处理输出取决于所选模块。 It can be following: Classification predictions... 后处理输出取决于所选模块。It can be following:· Classification predictions· Detection predictions· Pose estimation prediction· Video mask· Audio Sheet.127 或 或 Sheet.129 Sheet.130 Sheet.131 Sheet.132 Sheet.133 Sheet.134 Sheet.135 Sheet.136 Sheet.137 Sheet.138 Sheet.139 Sheet.140 Sheet.141 Sheet.142 Sheet.143 Sheet.144 Sheet.145 Sheet.146 Sheet.147 Sheet.148 Sheet.149 Sheet.150 Sheet.151 仅文件路径 仅文件路径 Sheet.152 Sheet.153 文件路径或 JSON 字符串 文件路径或JSON 字符串 Sheet.154 Sheet.155 Sheet.156 Sheet.157 最大结果 最大结果 Sheet.158 Sheet.159 Sheet.160 Sheet.161 模块名称 模块（名称） Sheet.162 Sheet.163 Sheet.164 Sheet.165 后处理模块 后处理模块 Sheet.166 Sheet.342 JSON 设置 JSON 设置 Sheet.343 标签文件 标签文件 Sheet.344 标签查找表 标签查找表 Sheet.345 Sheet.346 Sheet.347 Sheet.348 Sheet.349 Sheet.350 Sheet.351 Sheet.352 Sheet.353 Sheet.354 Sheet.355 Sheet.356 Sheet.357 Sheet.358 Sheet.359 Sheet.360 Sheet.361 Sheet.362 Sheet.363 Sheet.364 Sheet.365 Sheet.366 检测格式 检测格式 Sheet.368 JSON 解析器 JSON 解析器 Sheet.370 预定义颜色 预定义颜色 Sheet.372 社区解析器 社区解析器 Sheet.374 Sheet.375 Sheet.376 Sheet.377 Sheet.378 Sheet.379 Sheet.380 Sheet.381 Sheet.382 Sheet.383 Sheet.384 Sheet.385 Sheet.386 Sheet.387 Sheet.388 Sheet.389 Sheet.390 Sheet.391 Sheet.392 Sheet.393 Sheet.394 Sheet.395 Sheet.396 Sheet.397 Sheet.398 Sheet.399 Sheet.400 Sheet.401 Sheet.402 Sheet.403 Sheet.404 Sheet.405 Sheet.406 Sheet.407 Sheet.408 dlopen 模块 dlopen 模块 Sheet.409 Sheet.410 Sheet.411 Sheet.412 GetCaps GetCaps Sheet.413 配置 配置 Sheet.414 预测 预测 Sheet.430 GetCaps: Retrieve the module type and support tensors shape. ... · GetCaps: Retrieve the module type and support tensors shape.· Configure: Configure the module with path to labels file and settings in JSON format.· Process: Converts tensors to plugin specific format. ## 继承链 [GObject](https://docs.gtk.org/gobject/) → [GstObject](https://gstreamer.freedesktop.org/documentation/gstreamer/gstobject.html?gi-language=c) → [GstElement](https://gstreamer.freedesktop.org/documentation/gstreamer/gstelement.html?gi-language=c) → [GstBaseTransform](https://gstreamer.freedesktop.org/documentation/base/gstbasetransform.html?gi-language=c) →GstMLPostProcess 下表提供了有关 qtimlpostprocess 的端口模板和元素属性的信息。有关用例信息，请参见在 [Qualcomm Neural Processing SDK 用例](https://docs.qualcomm.com/doc/80-70022-50SC/topic/qualcomm-neural-processing-sdk-use-cases.html)和 [LiteRT 用例](https://docs.qualcomm.com/doc/80-70022-50SC/topic/tensorflow-lite-use-cases.html)中的分割使用案例。 ## 端口配置 | 端口名称 | 功能 | 功能 | 功能 | | --- | --- | --- | --- | | SINK 模板：'sink'
