Basic processing steps:

    private fun runTextRecognition(bitmap: Bitmap) {
        val image = FirebaseVisionImage.fromBitmap(bitmap)
        val recognizer = FirebaseVision.getInstance().onDeviceTextRecognizer

        recognizer.processImage(image).addOnSuccessListener {
            processTextRecognitionResult(it)
            isOcrImageFlowLocked = false
        }.addOnFailureListener { e: Exception ->
            e.printStackTrace()
            handleError(e)
            isOcrImageFlowLocked = false
        }
    }

    private fun processTextRecognitionResult(texts: FirebaseVisionText) {
        var txt = ""
        var maxFloat = 0f
        for (block in texts.textBlocks) {
            for (line in block.lines) {
                line.text.toFloatOrNull()?.let {
                    maxFloat = maxOf(maxFloat, it)
                }
                for (element in line.elements) {
                    txt += element.text + " "
                }
            }
        }
        Timber.d("Temperature Detected: $maxFloat")
        Timber.d("Text Detected: $txt")

        ocrImageObserver!!.value = if (floor(maxFloat) == ceil(maxFloat)) {
            maxFloat.toInt().toString()
        } else {
            maxFloat.toString()
        }

        if (maxFloat == 0f) {
            Toast.makeText(requireContext(), "No Numbers found", Toast.LENGTH_SHORT).show()
        }
    }
