Describe the actual behavior

always get empty threshold mask result when use vision task with image segmenter on Mobile and Mozilla desktop.

Cheked also with my custom js (using knockout)

this.filesetResolver = await FilesetResolver.forVisionTasks(data.visionWasmUrl);
this.hairSegmenter = await ImageSegmenter.createFromOptions(this.filesetResolver, {
                        baseOptions: {
                            modelAssetPath: [path_here],
                            delegate: "GPU"
                        },
                        outputCategoryMask: false,
                        outputConfidenceMasks: true,
                        runningMode: "VIDEO"
                    });

this.hairSegmenter.segmentForVideo(this.videoElementHTMLObject,startTimeMs,this.drawHair)


//a piece of code from drawHair function:

const mask = result.confidenceMasks[this.RESULT_HAIR_INDEX].getAsFloat32Array();
 for (let i = 0; i < mask.length; ++i) {
  if (mask[i] > 0.5) // ->>>>>  here mask[i] always = 0



even if open demo https://mediapipe-studio.webapps.google.com/demo/image_segmenter on Pixels or Mozilla it doesn't work

Describe the expected behaviour

As expected result I want to get a real hair mask result with not empty threshold

Standalone code/steps you may have used to try to get what you need

this.filesetResolver = await FilesetResolver.forVisionTasks(data.visionWasmUrl);
this.hairSegmenter = await ImageSegmenter.createFromOptions(this.filesetResolver, {
                        baseOptions: {
                            modelAssetPath: [path_here],
                            delegate: "GPU"
                        },
                        outputCategoryMask: false,
                        outputConfidenceMasks: true,
                        runningMode: "VIDEO"
                    });

this.hairSegmenter.segmentForVideo(this.videoElementHTMLObject,startTimeMs,this.drawHair)


//a piece of code from drawHair function:

const mask = result.confidenceMasks[this.RESULT_HAIR_INDEX].getAsFloat32Array();
 for (let i = 0; i < mask.length; ++i) {
  if (mask[i] > 0.5) // ->>>>>  here mask[i] always = 0

This is a related issue to google-ai-edge/mediapipe-samples#159. MPMask elements generated with GPU delegate are not yet supported on all platforms. We're working on patches for these issues now, but in the meantime, try using a CPU delegate-- that will be slower but should hopefully work in the meantime.

[annysmolyan]

For me it doesn't work in Mozilla even with CPU

[kuaashish]

@annysmolyan,

We have observed that image segmentation is functioning as expected in the Android Chrome Browser. Nevertheless, in the Mozilla browser, we cannot guarantee the functionality of the demo, as our testing has primarily focused on the browsers specified in the documentation.

We kindly request you to initiate a new feature request to include support for the Mozilla Browser, highlighting the potential benefits that the community could derive from such an enhancement. Furthermore, we intend to execute the demo on supported browsers and kindly request that you notify us if similar issues are encountered.

Moreover, we would appreciate your confirmation regarding the closure of this issue and the necessary status update, should it no longer be a concern from your end.

[opusonline]

Is there any way to detect GPU support for the current browser to set the correct options for delegate CPU/GPU?

Something like this would be very helpfull:

ImageSegmenter.getSupportedProcessingUnits() // returns a list like ['CPU', 'GPU']

Thanks!
