Match

Read-only recognition match result returned by region.find* helpers.

Syntax

Match

This class cannot be constructed directly.

Parameters

None

Returns

Behavior / side effects

Read-only recognition match result returned by region.find* helpers. In a recognition Success branch, Recognition.result points to the active Match or MatchList.

Execution

  • Blocking: Conditional
  • Thread safety: Not guaranteed
  • Parallel execution: Conditional

Execution cost and waits depend on the documented operation. Keep mutable values in their owning flow; sharing arbitrary objects between flows has no general thread-safety guarantee.

Example

m = Region(100, 200, 300, 400).find("btn", 3000)
if m.found:
    click(m)
    conf = m.confidence

# Recognition.result is only available in Python for the Recognition success branch.
if Recognition.result.found:
    click(Recognition.result, random=0)

Errors / limitations

No additional limitations documented; follow the parameter and behavior contract above.

Fields

NameDescription
nameString?
Matched target name. Template matches use the template name without extension, OCR uses the matched target text, and color matches use Color.
foundBoolean
Whether a match was found.
confidenceNumber
Confidence score from 0.0 to 1.0.
confNumber
Alias of confidence; returns the same score from 0.0 to 1.0.
pointPoint? | list[Point]
Match point. Image/OCR/object recognition usually returns Point; image matches below threshold can still return the best candidate point when bounds are available. Color and multi-target recognition can return list[Point] so match.point[0].x/y works for the best point.
boundsRegion?
Bounding box of the matched area. Image matches below threshold can still expose the best candidate bounds.
regionRegion?
Alias of bounds; returns the same matched Region or None.
inference_infodict?
Model or color metadata when available. TFLite metadata includes backend, class_id, class_name, preprocess_ms, inference_ms, postprocess_ms, total_ms, input_width, input_height, optional debug image dimensions, and capture telemetry. Detailed debug_result rows are shown only in the inference debug dialog. Color metadata includes backend=color, target_color, sampled_color, point, max_channel_delta, confidence, interval, match_count, and matches.
Field example
m = Region(100, 200, 300, 400).find("btn", 3000)
target_name = m.name
is_found = m.found
score = m.confidence
short_score = m.conf
center = m.point
box = m.bounds
same_box = m.region
info = m.inference_info
info_class_id = info.class_id
info_class_name = info.class_name

color_hit = Region(0, 0, 1080, 1920).find_color("#FFFFFF", tolerance=4)
color_name = color_hit.name
first_color_point = color_hit.point[0]

# In the Recognition success branch:
current = Recognition.result
if current.found:
    text(current.name)
    current.highlight(color="yellow", auto_hide_ms=800)

Methods

2 methods

Match.highlight

Draw a highlight frame for this match when found=true.

Syntax

match.highlight(color="green", line_width=2, region_width=36, auto_hide_ms=0)

Parameters

NameDescription
colorColor | String | Number
Highlight color.
Optional · Positional or named
Default: green
line_widthNumber
Outline width in pixels.
Optional · Positional or named
Default: 2
region_widthNumber
Fallback square width when the match only has point.
Optional · Positional or named
Default: 36
auto_hide_msNumber
Auto-hide timeout in milliseconds. 0 keeps highlight visible.
Optional · Positional or named
Default: 0

Returns

Match — Returns the same match after drawing highlight.

Behavior / side effects

Draw a highlight frame for this match when found=true. Uses bounds first; when bounds is missing, draws one square for each point in point/list.

Execution

  • Blocking: Conditional
  • Thread safety: Not guaranteed
  • Parallel execution: Conditional

Execution cost and waits depend on the documented operation. Keep mutable values in their owning flow; sharing arbitrary objects between flows has no general thread-safety guarantee.

Example

m = Region(100, 200, 300, 400).find("start", 3000)
m.highlight(color="yellow", line_width=3, auto_hide_ms=1200)

Errors / limitations

No additional limitations documented; follow the parameter and behavior contract above.

Match.highlight_off

Turn off the active highlight generated from this match instance.

Syntax

Parameters

None

Returns

Match — Returns the same match after turning highlight off.

Behavior / side effects

Turn off the active highlight generated from this match instance.

Execution
